Extend the stop-suppresses-restart mechanism to also work when stopping
individual language servers, not just "Stop All Servers".

Replace the single language_servers_stopped boolean with two fields:
- all_language_servers_stopped: set by Stop All Servers
- stopped_language_servers: tracks individually-stopped servers by name

When a user stops a specific language server, its name is recorded in the
stopped set. The three auto-start paths (buffer registration, server tree
refresh, settings-triggered restarts) now skip servers in this set.

Restarting a specific server clears it from the stopped set. Restart All
Servers clears both the global flag and the per-server set.

When the user clicks Stop All Servers, set a flag that suppresses
automatic language server startup. The flag is cleared when Restart
All Servers is hit. This guards the three auto-start paths:

- Buffer registration with language servers (new buffers, file path
  changes, language detection, language registry reloads)
- Server tree refresh (workspace config / manifest changes)
- Settings-triggered restarts (semantic token mode changes)

Also includes two other minor fixes for stdout info prints

This PR adjusts how project group removal works in the sidebar to be
project group aware. Removal is now a batched operation, and supports a
contextually appropriate fallback active workspace fallback. In the
process of removing this, I had to chase down and fix other broken code:
- Removes the "move to new window" actions
- Changed the sidebar to store things in "most recently added" order
- The recent project UI was still using workspaces, instead of project
groups
- Adjusted the archive command to use the new APIs to remove the
workspace associated with that worktree (cc: @rtfeldman)
- The property tests where still using indexes and workspaces instead of
project groups

After a user creates successfully creates a new git worktree we reset
the agent thread picker state to avoid accidentally creating a new
worktree for a thread.

This also fixes some bugs where a past agent thread picker state was
invalid because it became out of sync after a new worktree was created,
or when a mutating git operation occurred.

This PR adds spreadsheet-style independently resizable columns (dragging
changes total table width) and fixes scrolling issues in variable list
mode.

**What changed:**

- Adds `ResizableColumnsState` struct for independently resizable
columns (spreadsheet-style)
- Adds `ColumnWidthConfig::Resizable` variant for spreadsheet mode
- Adds `DraggedResizableColumn` drag payload type
- Adds `ResizableHeaderInfo` for double-click-to-reset functionality
- Adds `render_resize_handles_resizable` function for resize handles
rendering
- Adds horizontal scroll handle to `TableInteractionState`
- Adds `.on_drag_move::<DraggedResizableColumn>` handler to Table for
drag resizing

**Bug fixes:**

- Fixed missing vertical scrollbar in variable list mode
- Fixed half-broken scrolling in variable list mode (added
.measure_all() to make scrollbar aware of the height of the table)
- Moved vertical scrollbar to be pinned at the right side of the pane
with table — previously it was attached to the table content and was
pushed off-screen when table content was too wide

**API addition:**

```rust
// New variant added:
pub enum ColumnWidthConfig {
    Static { widths: StaticColumnWidths, table_width: Option<DefiniteLength> },
    Redistributable { entity: Entity<RedistributableColumnsState>, table_width: Option<DefiniteLength> },
    Resizable(Entity<ResizableColumnsState>),  // NEW: spreadsheet-style
}
```

**Callers updated:**

- csv_preview: Changed from `ColumnWidthConfig::redistributable()` to
use new resizable mode
- git_graph: Added `resizable_info` parameter

**Context:**

This is part 3 of a 3-PR series improving data table column width
handling:

1. [#51059](https://github.com/zed-industries/zed/pull/51059) - Extract
modules into separate files (mechanical change)
2. [#51120](https://github.com/zed-industries/zed/pull/51120) -
Introduce width config enum for redistributable column widths (API
rework)
3. **This PR**: Add independently resizable columns + fix variable list
scrolling (new feature + bug fixes)

The series builds on previously merged infrastructure:

- [#46341](https://github.com/zed-industries/zed/pull/46341) - Data
table dynamic column support
- [#46190](https://github.com/zed-industries/zed/pull/46190) - Variable
row height mode for data tables

Primary beneficiary: CSV preview feature
([#48207](https://github.com/zed-industries/zed/pull/48207))

This work is based on the [original draft PR
#44344](https://github.com/zed-industries/zed/pull/44344), decomposed
into reviewable pieces.

The "Hover Popover → Delay" setting item had its json_path set to
"hover_popover_enabled" (copy-paste error from the item above it),
introduced in #40739. This caused:

- "Copy Link" generating a wrong zed://settings/hover_popover_enabled
URL
- #hover_popover_delay filter returning no results in settings search
- Telemetry reporting delay changes as hover_popover_enabled

The pick/write closures were always correct, so the setting itself
functioned normally.

after the fix, filter works correctly

When a subagent was spawned while the parent had runtime-modified
settings (fast mode, thinking, etc.), the subagent would start with
defaults from `AgentSettings` instead of inheriting the parent's current
values.

This adds `inherit_parent_settings` as a single place in
`Thread::new_subagent` that copies all runtime-mutable settings from the
parent:

- `speed`
- `thinking_enabled`
- `thinking_effort`
- `summarization_model`
- `profile_id`

These are the same properties that `set_*` methods already propagate to
`running_subagents` — this fix ensures they're also inherited at
creation time.

Closes #ISSUE

Release Notes:

- Fixed a bug where a cleverly crafted directory name could lead to
remote code execution

This PR adjust the name of the worktree within the agent panel: we
display `main` if you're in the main worktree and then the worktree name
when in a linked one. Additionally, I also took the opportunity to fix
something that confused me in the general worktree picker: for the list
item that represented the main worktree, we were using the current
checked out branch name for that item's name. I think that's a bit
incorrect, given the _name_ of that worktree isn't the name of the
branch you have active at that moment. For now, I'm using simply `main`
as the worktree name. Lastly, also added a little blue check icon in the
worktree _and branch_ picker to highlight which worktree/branch is
currently active.

### Summary

Keep the prompt editor’s max-width centering, but move the footer
controls out of the same flexible wrapper as the full-height editor and
add `min_h_0()` shrink guards so the editor no longer overlaps the
footer in zoomed/full-screen mode.

Syncs the models docs page with what `crates/billing/src/plans.rs` and
`crates/llm_api/src/features/list_models.rs` actually serve.

## Changes

**New models added:**
- GPT-5.4 pro (Pro/Business only): $30/$180 input/output, no cache, 400k
context
- GPT-5.4: $2.50/$15 input/output, $0.025 cached, 400k context
- GPT-5.3-Codex: $1.75/$14 input/output, $0.175 cached, 400k context

**Pricing corrected:**
- GPT-5.2 + GPT-5.2-Codex: input $1.25 → $1.75, output $10 → $14, cached
$0.125 → $0.175
- Gemini 3 Flash: input $0.30 → $0.50, output $2.50 → $3.00

**Other fixes:**
- Student plan note updated to include GPT-5.4 pro restriction
- Grok context windows added to the context window table (128k / 256k
for Grok Code Fast 1)
- "GPT-5.2 Codex" renamed to "GPT-5.2-Codex" to match `display_name` in
code
- Removed retired "Gemini 3 Pro" from context window footnote

Release Notes:

- N/A

When filtering themes with a query that matches nothing (e.g., "zzz"),
`show_selected_theme` returned `None` and overwrote `selected_theme`.
Clearing the filter then lost track of the previous selection and
defaulted to index 0.

The fix only updates `selected_theme` when `show_selected_theme` returns
`Some`. Same change in both the theme selector and the icon theme
selector.

## Context

When `update_matches` runs a filter that yields zero results,
`show_selected_theme` returns `None`. The old code unconditionally
assigned that back to `selected_theme`, wiping out the previous
selection. When the user clears the filter, the selector falls into the
`query.is_empty() && selected_theme.is_none()` branch and resets to
index 0 instead of restoring the original pick.

## How to review

The fix is the same one-line change in two files:
1. `crates/theme_selector/src/theme_selector.rs` — line 458
2. `crates/theme_selector/src/icon_theme_selector.rs` — line 272

The rest is test infrastructure:
3. `crates/theme/src/registry.rs` — `register_test_themes` /
`register_test_icon_themes` helpers
4. Tests in both selector files covering the empty filter → clear filter
flow

Before, every creation of `AnchorSeekTarget` called
`MultiBufferSnapshot::buffer_for_path`, which seeks the excerpts sum
tree. Now we avoid that by

- looking up the buffer snapshot for the anchor's buffer in the
`buffers` map (keyed by `BufferId`)
- handling the case where the anchor's buffer doesn't exist at the
original path key with a separate `AnchorSeekTarget::Missing` variant

We also added a separate optimization to `AnchorSeekTarget::cmp`, to
skip the full `PathKey` comparison when the cursor's `PathKeyIndex` is
the same as the anchor's. This should help with singleton multibuffers.

Closes #39532

## Summary

Move the long-running agent "generating" spinner into a dedicated
`GeneratingSpinner` view.

Previously, the generating state rendered `SpinnerLabel` inline as part
of the full thread view. This change keeps the same spinner styling, but
isolates it into its own small view so the animation no longer needs to
live directly inside the larger thread UI subtree while the agent is
running.

Properly deserializes the app_port field, even if it is an array of
strings. Also, removes app_port from consideration when building a
docker-compose-based dev container, since the spec specifies that it
only applies to non-docker-compose dev containers.

Release Notes:

- Fixed app_port deserialization in dev container

Update macOS and Linux's default keymaps such that, in the `Terminal`
context, `ctrl-r` does send the `ctrl-r` keystrokes. This was no longer

When a project mixes main repo worktrees (e.g. `extensions`) with linked
git worktrees (e.g. `zed4`, a linked worktree of `zed`), two things were
broken:

1. **Threads appeared under the wrong sidebar heading.** A thread
created in a workspace with both `extensions` and `zed4` would show
under the "zed" group instead of the "extensions, zed" group. This
happened because `main_worktree_paths` in `ThreadMetadata` was only
populated with paths from linked worktrees, omitting regular repos
entirely. The fix uses `project_group_key()` to normalize all visible
worktrees to their main repo paths — the same normalization the sidebar
uses for group headers.

2. **The worktree chip tooltip only showed linked worktree paths**,
missing main repo paths like `extensions`. This happened because
`worktree_info_from_thread_paths` filtered out main worktree paths
entirely. The fix introduces a `WorktreeKind` enum (`Main` / `Linked`)
on `ThreadItemWorktreeInfo`, so all worktrees are included in the data
model. Chips still only render for `Linked` worktrees (main worktrees
are redundant with the group header), but the tooltip now shows all
paths.

After chat functionality was removed, this panel became redundant. It
only displayed three notification types: incoming contact requests,
accepted contact requests, and channel invitations.

This PR moves those notifications into the collab experience by adding
toast popups and a badge count to the collab panel. It also removes the
notification-panel-specific settings, documentation, and Vim command.

Before you mark this PR as ready for review, make sure that you have:
- [ ] Added a solid test coverage and/or screenshots from doing manual
testing
- [x] Done a self-review taking into account security and performance
aspects
- [x] Aligned any UI changes with the [UI
checklist](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist)

Release Notes:

- Removed the notification panel from Zed

Extend the DeploySearch action to accept additional parameters for
configuring the project search from keymaps:

- query: prefilled search query string
- regex: enable regex search mode
- case_sensitive: match case exactly
- whole_word: match whole words only
- include_ignored: search in gitignored files

With this change, the following keymap becomes possible:

```json
["pane::DeploySearch", { "query": "TODO|FIXME|NOTE|BUG|HACK|XXX|WARN", "regex": true }],
```

Release Notes:

- Added options to `pane::DeploySearch` for keymap-driven search
initiation

This PR improves the recent projects picker in the context of
multi-workspace:

- The currently active project now appears in the "This Window" section
with a checkmark indicator. Clicking it simply dismisses the picker,
since there's nothing to switch to. This feels like a better UX because
it gives you visual confirmation of where you are.
- The remove button is hidden for the current project entry, both in the
row and the footer, to prevent accidentally removing the workspace
you're actively using.
- The "Add to Workspace" button now uses a more descriptive icon
(`FolderOpenAdd`) and shows a meta tooltip clarifying that it adds the
project as a multi-root folder project.

The primary click/enter behavior remains unchanged—it opens the selected
project in the current window's multi-workspace. The "Open in New
Window" action continues to be available via the icon button or
shift+enter.

Release Notes:

- Improved the recent projects picker to show the currently active
project in the "This Window" section with a checkmark indicator.

- `language_model` no longer depends on provider-specific crates such as
`anthropic` and `open_ai` (inverted dependency)
- `language_model_core` was extracted from `language_model` which
contains the types for the provider-specific crates to convert to/from.
- `gpui::SharedString` has been extracted into its own crate (still
exposed by `gpui`), so `language_model_core` and provider API crates
don't have to depend on `gpui`.
- Removes some unnecessary `&'static str` | `SharedString` -> `String`
-> `SharedString` conversions across the codebase.
- Extracts the core logic of the cloud `LanguageModelProvider` into its
own crate with simpler dependencies.

I was testing out the changes in
https://github.com/zed-industries/zed/pull/52730 and realized that the
agent panel, when full screen, would be auto-dismissed if I toggled the
sidebar off. Turns out this happens because we were "hard-coding" the
focus back to the center pane, which was automatically dismissing zoomed
items. So, in this PR, I essentially am copying the ModalLayer approach
of storing whatever was focused before so we can return focus back to it
if possible.

Closes #50212

There are two unreasonable coupling account for this issue, the coupling
of `use_tree_sitter` with `languge_aware` in

https://github.com/zed-industries/zed/blob/7892b932795911516f26f3c1c1c72249ed181ba8/crates/editor/src/element.rs#L3820-L3822
and the coupling of `language_aware` with `diagnostics` in
https://github.com/zed-industries/zed/blob/7892b932795911516f26f3c1c1c72249ed181ba8/crates/language/src/buffer.rs#L3736-L3746

Because of these couplings, when the editor stops using Tree-sitter
highlighting when `"semantic_tokens"` set to `"full"`, it also
accidentally stops fetching diagnostic information. This is why error
and warning underlines disappear.

I’ve fixed this by adding a separate `use_tree_sitter` parameter to
`highlighted_chunks`. This way, we can keep `language_aware` true to get
the diagnostic data we need, but still decide whether or not to apply
Tree-sitter highlights. I chose to fix this at the `highlighted_chunks`
level because I’m worried that changing the logic in the deeper layers
of the DisplayMap or Buffer might have too many side effects that are
hard to predict. This approach feels like a safer way to solve the
problem.

Release Notes:

- Fixed a bug where diagnostic underlines disappeared when
"semantic_tokens" set to "full"

Follow-up to https://github.com/zed-industries/zed/pull/53290

This PR fixes a mistake I pushed before of making the `ListItem`'s
height method take pixels instead of a scalable unit like rems. Now, it
takes `DefiniteLength` which can house both values, meaning we should be
clear to set an explicit height for all of these items while still
preserving font-size scaling.

Release Notes:

- N/A

This PR adds a configurable max-width to the agent panel. This will be
particularly useful when opting into an agentic-first layout where the
thread will be at the center of the UI (with the panel most likely
full-screen'ed, which is why I'm also adding here the button to make it
full screen in the toolbar). The default max-width is 850, which is a
bit bigger than the one generally considered as a standard (~66
characters wide, which usually sums up to 750 pixels).

Release Notes:

- Agent: Added a max-width to the thread view for better readability,
particularly when the panel is zoomed in.

Closes #51466

 Release Notes:

- Fixed mermaid diagrams not showing text in markdown preview by
bundling fallback fonts and fixing generic font family resolution in the
SVG renderer.

Update how `workspace::pane::Pane` handles the `RevealInProjectPanel`
action so as to display a notification when the user attempts to reveal
an unsaved buffer or a file that does not belong to any of the open
projects.

Closes #23967 

Release Notes:

- Update `pane: reveal in project panel` to display a notification when
the user attempts to use it with an unsaved buffer or a file that is not
part of the open projects

This PR allows users to create a new thread based off a git worktree
that already exists or has a custom name. User's can also choose what
branch they want the newly generated worktree to be based off of.

The UI still needs some polish, but I'm merging this early to get the
team using this before our preview launch. I'll be active today and
tomorrow before launch to fix any nits we have with the UI.

Functionality of this feature works! And I have a basic test to prevent
regressions

## What This PR Does
This PR adds support for HTML alignment styles to be applied to
Paragraph and Heading elements and their children. Here is what this
looks like before vs after this PR (both images use the same markdown
below):

```markdown
<p style="text-align: center;">
  <a target="_blank" href="https://github.com/"><img width="150" height="150" src="https://upload.wikimedia.org/wikipedia/commons/c/c2/GitHub_Invertocat_Logo.svg"></a>
</p>
```

**BEFORE:**

<img width="742" height="242" alt="image"
src="https://github.com/user-attachments/assets/4ca8b8d9-0606-45f5-8a0e-cafaaac47d97"
/>

**AFTER:**

<img width="1274" height="267" alt="image"
src="https://github.com/user-attachments/assets/2c347ce7-75b9-4ef6-9598-b1eda7272ef5"
/>

## Notes
I used `style="text-align: center|left|right;"` instead of
`align="center|right|left"` since `align` has been [deprecated in
HTML5](https://www.w3.org/TR/2011/WD-html5-author-20110809/obsolete.html)
for block-level elements. The issue this PR solves mentioned that github
supports the `align="center|right|left"` attribute, so I'm unsure if the
Zed team would want to have parity there. Feel free to let me know if
that would be something that should be added, however for now I've
decided to follow the HTML5 standard.
