This brings the terminal element's viewport culling in line with the editor
optimization in PR #44995 and the fix in PR #45077.

## Problem

When a terminal is inside a scrollable container (e.g., the Agent Panel
thread view), it would render ALL cells during prepaint, even when the
terminal was entirely outside the viewport. This caused unnecessary CPU
usage when multiple terminal tool outputs existed in the Agent Panel.

## Solution

Calculate the intersection of the terminal's bounds with the current
content_mask (the visible viewport after all parent clipping). If the
intersection has zero area, skip all cell processing entirely.

### Important distinction between content modes:

- **ContentMode::Scrollable**: Cells use the terminal's internal coordinate
  system with negative line numbers for scrollback history. We cannot filter
  cells by screen-space row numbers, so we render all cells when visible.
  The early-exit for zero intersection handles the offscreen case.

- **ContentMode::Inline**: Cells use 0-based line numbers (no scrollback).
  We can filter cells to only those in the visible row range, using the
  same logic that existed before but now extracted into a helper function
  with proper bounds clamping to prevent the hang bug from PR #45077.

## Testing

Added comprehensive unit tests for:
- compute_visible_row_range edge cases
- Cell filtering logic for Inline mode
- Line/i32 comparison behavior

Manually verified:
- Terminal fully visible (no clipping)
- Terminal clipped from top/bottom
- Terminal completely outside viewport (renders nothing)
- Scrollable terminals with scrollback history work correctly

Release Notes:

- Improved Agent Panel performance when terminals are scrolled offscreen.

Follow up to https://github.com/zed-industries/zed/pull/45440 adding an
item for "Open Thread as Markdown" and another for scroll to top and

In https://github.com/zed-industries/zed/pull/45440, we're implementing
the ability to right-click in the agent panel and copy the rendered
markdown. However, that presented itself as not as straightforward as
just making the menu item fire the `CopyAsMarkdown` action because any
selection in markdown is cleared after a new mouse click, and for the
right-click copy menu item to work, we need to persist that selection
even after the menu itself is opened and the "Copy" menu item is
clicked.

This all demanded a bit of work in the markdown file itself, and given
we may want to use this functionality for other non-agent thread view
markdown use cases in the future, I felt like it'd be better breaking it
down into a separate PR that we can more easily track in the future.

The context menu still needs to be built in the place where the markdown
is created and rendered, though. This PR only adds the infrastructure
needed so that this menu can simply fire the `CopyAsMarkdown` and make
the copying work.

This PR adds the ability to favorite models for external agents—writing
to the settings in the `agent_servers` key—as well as a handful of other
improvements:

- Make the cycling keybinding `alt-enter` work for the inline assistant
as well as previous user messages
- Better organized the keybinding files removing some outdated
agent-related keybinding definitions
- Renamed the inline assistant key context to "InlineAssistant" as
"PromptEditor" is old and confusing
- Made the keybindings to rate an inline assistant response visible in
the thumbs up/down button's tooltip
- Created a unified component for the model selector tooltip given we
had 3 different places creating the same element
- Make the "Cycle Favorited Models" row in the tooltip visible only if
there is more than one favorite models

Release Notes:

- agent: External agents also now support the favoriting model feature,
which comes with a handy keybinding to cycle through the favorite list.

## Documentation Update Summary

### Changes Made

| File | Change | Related Code |
| --- | --- | --- |
| `docs/src/ai/edit-prediction.md` | Updated Codestral setup
instructions to use Settings Editor path instead of outdated
`agent::OpenSettings` action reference | Settings Editor provider
configuration flow |

### Rationale

The primary documentation update addresses outdated instructions in the
Codestral setup section. The original text referenced an
`agent::OpenSettings` action that directed users to an "Agent Panel
settings view" which no longer reflects the current UI flow. The updated
instructions now guide users through the Settings Editor with
platform-specific keyboard shortcuts and provide an alternative status
bar path.

### Review Notes

- **Codestral instructions**: Reviewers should verify the Settings
Editor navigation path (`Cmd+,` → search "Edit Predictions" →
**Configure Providers**) matches the current Zed UI
- **Status bar alternative**: The alternative path via "edit prediction
icon in the status bar" should be confirmed as accurate

## Documentation Update Summary

### Changes Made
| File | Change | Related Code |
| --- | --- | --- |
| docs/src/ai/agent-panel.md | Added documentation for `agent::PasteRaw`
action, explaining automatic @mention formatting for pasted code and how
to bypass it | PR #45254 |

### Rationale
PR #45254 ("agent_ui: Improve UX when pasting code into message editor")
introduced the `agent::PasteRaw` action, which allows users to paste
clipboard content without automatic formatting. When users copy
multi-line code from an editor buffer and paste it into the Agent panel,
Zed now automatically formats it as an @mention with file context. The
`PasteRaw` action provides a way to bypass this behavior when raw text
is preferred.

This documentation update ensures users can discover both:
1. The new automatic @mention formatting behavior
2. The keybinding to bypass it when needed

### Review Notes
- The new paragraph was placed in the "Adding Context" section,
immediately after the existing note about image pasting support—this
maintains logical flow since both relate to pasting behavior
- Uses the standard `{#kb agent::PasteRaw}` syntax for keybinding
references, consistent with other keybinding documentation in the file
- The documentation passed Prettier formatting validation without
modifications

---

### Condensed Version (for commit message)
```
docs(agent-panel): Document PasteRaw action for bypassing auto @mention formatting

automatically formatted as @mentions, with keybinding to paste raw text.

Release Notes:

- Fixed dock panel button tooltips not being dismissed when toggling
panels via keyboard shortcut




**Problem:** When hovering over a dock panel button and using a keyboard
shortcut to toggle the panel, the tooltip remains visible with stale
content. This is inconsistent with mouse click behavior, where the
tooltip is dismissed on mouse down.

**Solution:** Include the panel's active state in the button's element
ID. When the state changes, the element ID changes (e.g., `"DebugPanel"`
→ `"DebugPanel-active"`), which causes GPUI to discard the old element
state including the cached tooltip.

**Testing:** Manually verified:
1. Hover over a dock panel button, wait for tooltip
2. Press keyboard shortcut to toggle the panel
3. Tooltip is now dismissed (consistent with mouse click behavior)

Draft as a base for continuing the discussion in #8008 : adds a
`SplitOperation` enum to support bindings like `["pane::SplitLeft",
{"operation": "Clear"}]`

To be discussed @MrSubidubi and others:

- Naming: Generally not happy with names yet and specifically `Empty` is
unclear, e.g., what does this mean for terminal panes? Added placeholder
code to split without cloning, but unsure what users would expect in
this case.
- ~~I removed `SplitAndMoveXyz` actions but I guess we should keep them
for backwards compatibility?~~
- May have missed details in the move implementation. Will check the
code again for opportunities to refactor more code after we agree on the
approach.
- ~~Tests should go to `crates/collab/src/tests/integration_tests.rs`?~~

Closes #8008

Release Notes:

- Add `pane::Split` mode (`{ClonePane,EmptyPane,MovePane}`) to allow
creating an empty buffer.

/>


## Open Questions(Would be nice to get some advice here)
- Binary Fetching:
- I'm pretty sure the binary fetching is suboptimal. The main problem
here was getting access to the delegate but i figured that out
eventually in a way that i _hope_ should be fine.
- The toolchain and binary options can differ from what the user has
configured potentially leading to mismatches in the autocomplete values
returned(these are probably rarely changed though). I could not really
find a way to fetch these in this context so the provided ones are for
now just `default` values.
- For the trait API it is just provided a binary, since i wanted to use
the potentially cached binary from the CachedLspAdapter. Is that fine
our should the arguments be passed to the LspAdapter such that it can
potentially download the LSP?
- As for those LSPs with JSON schema files in their repositories i can
add the files to zed manually e.g. in
languages/language/initialization_options_schema.json, which could cause
mismatches with the actual binary. Is there a preferred approach for Zed
here also with regards to updating them?

- Fixed spurious "no checkpoint" error in agent panel

---

## Summary

`update_last_checkpoint` would call `last_user_message()` twice - once
at the start to capture the checkpoint, and again in an async closure
after the checkpoint comparison completed. If a new user message without
a checkpoint was added between these two calls, the second call would
find the new message and fail with "no checkpoint".

## Fix

Capture the user message ID at the start and use `user_message_mut(&id)`
in the async closure to find the specific message.

This PR fixes two issues with regards to markdown codeblocks rendered in
tool call input and output content display:
- the JSON code snippets weren't properly indented
- codeblocks weren't being rendered in unique containers; e.g., if you
hovered one scrollbar, all of them would also be hovered, even though
horizontal scrolling itself worked properly

Here's the end result:


https://github.com/user-attachments/assets/3d6daf64-0f88-4a16-a5a0-94998c1ba7e2

Release Notes:

- agent: Fix scrollbar and JSON indentation for tool call input/output
content's markdown codeblocks.

- Make the buttons capable of changing the editor's content
(incrementing or decrementing the value)
- Make arrow key up and down increment and decrement the editor value
- Tried to apply a bit of DRY here by creating some functions that can
be reused across the buttons and editor given they all essentially do
the same thing (change the value)
- Fixed an issue where the editor would not allow focus to move
elsewhere, making it impossible to open a dropdown, for example, if your
focus was on the number field's editor

Closes https://github.com/zed-industries/zed/issues/43208

This PR essentially unblocks the editable number field. The function
that shapes editor lines was hard-coding text alignment to the left,
meaning that whatever different alignment we'd pass through
`EditorStyles`would be ignored. To solve this, I just added a text align
and align width fields to the line paint function and updated all call
sites keeping the default configuration. Had to also add an
`alignment_offset()` helper to make sure the cursor positioning, the
selection background element, and the click-to-focus functionality were
kept in-sync with the non-left aligned editor.

Then... the big star of the show here is being able to add the `mode`
method to the number field, which uses `TextAlign::Center`, thus making
it work as we designed it to work.

Currently on x11, gpui PopUp windows only rely on the "notification"
type in order to indicate that they should spawn as floating window.
Several window managers (leftwm in my case, but it also seems to be the
case for dwm and ratpoison) do not this property into account thus not
spawning them as float. On the other hand, using Floating instead of
PopUp do make those windows spawn as floating, as these window manager
do take into account the (older) "dialog" type.

The [freedekstop
documentation](https://specifications.freedesktop.org/wm/1.5/ar01s05.html#id-1.6.7)
does seem to suggest that these windows should also have the override
redirect property :
> This property is typically used on override-redirect windows. 

Note that this also disables pretty much all interactions with the
window manager (such as moving the window, resizing etc...)

This fixes an X11 scrolling issue where Zed may jump by a large amount
due to the scroll valuator state not being reset when the window loses
focus. If you Alt-Tab away from Zed, scroll in another application, then
return, the first scroll event in Zed applies the entire accumulated
delta instead of a single step.

The missing FocusOut reset was originally identified in issue #34901.

Resetting scroll positions on FocusOut matches the behavior already
implemented in the XinputLeave handler and prevents this jump.

Closes #34901
Closes #40538

Release Notes:

- Fixed an X11 issue where Alt-Tabbing to another application,
scrolling, and returning to Zed could cause the next scroll event to
jump by a large amount.

I've just enriched the existing tab_stop.rs example for GPUI with a
demonstration of tab_group. I don't think tab groups existed when the
original example was written.

(I didn't understand the behaviour for tab_group from the doccomments
and the example was missing, so I think this is a productive PR)

The failure would happen if the current version of the file was open as
an editor. This happened because the git blob and current version of the
buffer would have the same `ProjectPath`.

The fix was adding a new `DiskState::Historic` variant to represent
buffers that are past versions of a file (usually a snapshot from
version control). Historic buffers don't return a `ProjectPath` because
the file isn't real, thus there isn't and shouldn't be a `ProjectPath`
to it. (At least with the current way we represent a project path)

I also change the display name to use the local OS's path style instead
of being hardcoded to Posix, and cleaned up some code too.

## Problem

When users paste or drag large images into the agent panel, the encoded
payload can exceed upstream provider limits (e.g., Anthropic's 5MB
per-image limit), causing API errors.

## Solution

Enforce a default 5MB limit on encoded PNG bytes in
`LanguageModelImage::from_image`:

1. Apply existing Anthropic dimension limits first (1568px max in either
dimension)
2. Iteratively downscale by ~15% per pass until the encoded PNG is under
5MB
3. Return `None` if the image can't be shrunk within 8 passes
(fail-safe)

The limit is enforced at the `LanguageModelImage` conversion layer,
which is the choke point for all image ingestion paths (agent panel
paste/drag, file mentions, text threads, etc.).

## Future Work

The 5MB limit is a conservative default. Provider-specific limits can be
introduced later by adding a `from_image_with_constraints` API.

## Testing

Added a regression test that:
1. Generates a noisy 4096x4096 PNG (guaranteed >5MB)
2. Converts it via `LanguageModelImage::from_image`
3. Asserts the result is ≤5MB and was actually downscaled
