### Fixes #31865

### Problem
When navigating a picker (command palette, file finder, etc.) with the
keyboard and then hovering with the mouse, two items would appear
highlighted at the same time - one from the keyboard selection
ghost_element_selected background and one from the CSS style
ghost_element_hover background. This happened because GPUI's CSS hover
is applied at paint time independently from the Rust selection state.

### Solution
Added a keyboard_navigated: bool flag to [Picker] to track whether the
last navigation was via keyboard or mouse.

When a keyboard navigation action fires (↑, ↓, Home, End, etc.),
`keyboard_navigated` is set to true. A transparent
`block_mouse_except_scroll` overlay div is added on top of each list
item, preventing the CSS style from firing on `ListItem` children.

When the mouse moves over any item, the overlay's `on_mouse_move`
handler fires, clears keyboard_navigated, moves the selection to that
item, and re-renders - removing all overlays and restoring normal mouse
hover behavior.
The `on_hover` handler also moves the selection to whichever item the
mouse enters, so mouse navigation is fully functional.
Clicks work through the overlay since `block_mouse_except_scroll` only
affects hover hit-testing, not click events on the parent div.

### Behavior
Matches VS Code / IntelliJ — keyboard navigation suppresses hover
highlights until the mouse moves, at which point normal hover resumes.
Only one item is ever highlighted at a time.

Fixes https://github.com/zed-industries/zed/issues/50218

- For every `Host` block: collect its host patterns (handling
continuations and filtering `!`/`*/\`), remember any `Hostname`.
- When the block ends: if `Hostname` is a git provider → discard
everything.
- Else if `Hostname` exists → keep all host aliases.
- Else → keep only the host aliases that are not git providers.

Added more extensive test coverage as well to cover the above!

gitlab.com) from SSH config.

Fixes #51778

#### Fix

- Add `EINVAL` to the list of error codes that trigger the
metadata-based rename fallback in `crates/fs/src/fs.rs`
- FUSE filesystems (NTFS via ntfs-3g, exFAT, etc.) return `EINVAL` when
`renameat2` is called with `RENAME_NOREPLACE`, since they don't support
the flag.
- The existing fallback already handles `ENOSYS`, `ENOTSUP`, and
`EOPNOTSUPP` for similar unsupported-operation cases.

The tab context menu has "Copy Path", "Open in Terminal", and "Reveal In
Project Panel" but no way to reveal the file in the system file manager.
This action already exists in three other context menus (editor
right-click, project panel, outline panel) but was missing from tab
right-click.

## Changes

Adds a platform-specific entry to the tab context menu:
- **macOS:** "Reveal in Finder"
- **Windows:** "Reveal in File Explorer"
- **Linux:** "Reveal in File Manager"

Placed after "Copy Relative Path" and before "Pin Tab". Gated behind
`is_local` (including WSL with host interop) to match the project
panel's behavior. Uses the existing `project.reveal_path()`
infrastructure, which handles platform-specific file manager invocation
and WSL path conversion.

## Prior art

Every major editor has this in the tab context menu:
- VS Code: "Reveal in Finder" (macOS) / "Reveal in File Explorer"
(Windows)
- JetBrains IDEs: Right-click tab -> "Open in" -> "Finder"
- Sublime Text: Right-click tab -> "Reveal in Finder"

Zed already has this in the editor body right-click menu (`Cmd-K R`),
project panel (`Alt-Cmd-R`), and outline panel. The tab context menu was
the only place it was missing.

This contribution was developed with AI assistance (Claude Code).

Release Notes:

- Added "Reveal in Finder" to the tab context menu

Part of #29026

## Summary

https://github.com/user-attachments/assets/35b4f969-1fcf-45f4-88cd-cbc27ad9696e

macOS Finder places file paths on the system pasteboard using
`NSFilenamesPboardType` when files are copied. Previously, the project
panel only supported its own internal clipboard for copy/cut/paste
operations and ignored system clipboard content entirely. This meant
that copying files in Finder and pasting them in Zed's project panel did
nothing.

This PR adds support for reading file paths from the macOS system
pasteboard, enabling a natural workflow where users can copy files in
Finder (or other file managers) and paste them directly into Zed's
project panel.

> **Note:** Pasting files from a system file manager currently only
works on macOS. The project panel changes are cross-platform, but the
clipboard reading of file paths (`ExternalPaths`) is only implemented in
the macOS pasteboard. Windows and Linux would need equivalent changes in
their respective platform clipboard implementations to support this.
Copying/cutting files from the project panel to the system clipboard as
plain text works on all platforms.

### Changes

**`crates/gpui/src/platform/mac/pasteboard.rs`**
- Read `NSFilenamesPboardType` from the system pasteboard and surface
file paths as `ClipboardEntry::ExternalPaths`
- Check for file paths before plain text, since Finder puts both types
on the pasteboard (without this priority, file paths would be returned
as plain text strings)
- Extract the string-reading logic into `read_string_from_pasteboard()`
to allow reuse

**`crates/project_panel/src/project_panel.rs`**
- On paste, check the system clipboard for external file paths and use
the existing `drop_external_files` mechanism to copy them into the
project
- On copy/cut, write the selected entries' absolute paths to the system
clipboard so other apps can consume them
- Update the "Paste" context menu item to also be enabled when the
system clipboard contains file paths, not just when the internal
clipboard has entries

## Test plan

- [ ] Copy one or more files in Finder, paste in the project panel —
files should be copied into the selected directory
- [ ] Copy files within the project panel, paste — existing internal
copy/paste behavior is preserved
- [ ] Cut files within the project panel, paste — existing internal
cut/paste behavior is preserved
- [ ] Copy files in the project panel, paste in Finder or another app —
paths are available as plain text
- [ ] Right-click context menu shows "Paste" enabled when system
clipboard has file paths
- [ ] Right-click context menu shows "Paste" disabled when both internal
and system clipboards are empty

Release Notes:

- Added support for pasting files from Finder (and other file managers)
into the project panel via the system clipboard (macOS only). Copying or
cutting files in the project panel now also writes their paths to the
system clipboard for use in other apps.

All of the important changes are in
[`db.rs`](https://github.com/zed-industries/zed/pull/51809/changes#diff-2f644eab943bfa58feec29256281a3d9e8d4d7784cd34783e845af8beb15b16d).
Consider reading the commit log in order to review this work.

The DB crate's macro and API was changed to fix flakiness observed in
the MultiWorkspace tests when run locally. This flakiness was caused by
a shared `static LazyLock`, that caused concurrent test runs to interact
with the same underlying in-memory database. This flakiness wasn't
possible on CI due to it's usage of `cargo nextest`, whose
process-per-test approach masked this problem.

Essentially, I've changed the `static_connection` macro to remove the
static database variable and redone the internal model. Now, all
database types are thin wrappers around a generic `AppDatabase`. The
`AppDatabase` collects all of the individual table's migrations via the
`inventory` crate, and so only runs the migrations once on startup,
rather than a dozen times on startup.

The new API requires a `cx` so that we can replace the database returned
at runtime, rather than relying exclusively on a process-global
thread-local. However, we are still using a `static LazyLock` so that we
only need to take an `&App`, instead of an `&mut App`. These databases
types are `Clone + Send + Sync`, so you can easily capture-and-move the
database into background tasks and other places that don't have a `cx`.

For tests that require database isolation, it is now possible to set
their own database in init. See
[`workspace::init_test`](https://github.com/zed-industries/zed/pull/51809/changes#diff-041673bbd1947a35d45945636c0055429dfc8b5985faf93f8a8a960c9ad31e28R13610),
for the flakiness fix.

Best part, this change should be entirely compiler driven, so the Zed
agent was able to make the app-wide refactor easily.

when a resizing configure event is throttled (skipped to limit redraws
to once per vblank) the xdg_surface serial was never acknowledged. the
early return bypassed the ack_configure call that follows the throttle
check, violating the xdg-shell protocol requirement that every configure
serial be acknowledged before the next surface commit.

fix by calling ack_configure before the early return so the compositor
always receives the acknowledgment, dosent matter whether the resize
itself is applied.

Fixes #51542

Adds a `git_panel.starts_open` setting for parity with `project_panel`.
When set to `true`, the git panel opens automatically in new workspaces
that don't have saved panel state.

The default is `false`, matching current behavior (non-breaking).

### Usage

```json
{
  "git_panel": {
    "starts_open": true
  }
}
```

### Implementation

Follows the same pattern as `project_panel.starts_open`:

1. `GitPanelSettingsContent` - added `starts_open: Option<bool>` to the
settings schema
2. `GitPanelSettings` - added `starts_open: bool` field
3. `GitPanel` Panel impl - overrides `starts_open()` to read from
settings

Release Notes:

- Added `git_panel.starts_open` setting to control whether the git panel
opens automatically in new workspaces (default: false)

The conversations on Grok 4 were failing right away on the first message
in a conversation when using Zed provided model directly, but not the
xAI API directly.

The reason we were seeing this is that when sending the JSON schemas for
built-in tools to the cloud API, we didn't use the transform we use for
xAI in a BYOK context. The xAI API doesn't support the full JSON schema
spec, and specifically for the spawn_agent tool, we were generating a
`oneOf` type for a field. Applying that transformation in the cloud case
too fixes the issue.

Release Notes:

- Fixed broken (failing on first message) xAI models over the Zed
provider on profiles using the spawn_agent tool, including the default
Ask and Write profiles.

While fixing the tests in the previous PR (#48338), I noticed that the
`delete_branch` tests only verified the UI state changes rather than the
actual state of the underlying repository.

Currently, if `delete_branch` were a no-op that returned Ok(), the tests
would still pass incorrectly. This PR addresses that gap by ensuring the
branch is actually removed from the repository.

Hello! This is a feature that I really wanted, so I've created an
implementation of it. Hope u guys like it.
It was alto mentioned at [this
discussion](https://github.com/zed-industries/zed/discussions/30473)

The use cases were based on the [vscode
extension](https://marketplace.visualstudio.com/items?itemName=yo1dog.cursor-align)
(only spaces case was implemented)
- The algorithm is O(n + m × 2k), where:
- n = total cursors (for initial analysis, to understand how many
alignments will be performed)
  - m = number of alignment columns  
- k = number of alignment rows (first time to get the most-right
occurrence, the next one to create the `Vec` of edits)


Release Notes:

- Added `editor: align selections` command

Ensure that the `vim::visual::Vim::visual_block_motion` method is called
when `scroll_editor` is called while in Visual Block mode. This fixes an
issue where, after getting into `Visual Block` mode, if the user used
`ctrl-d` or `ctrl-u` to scroll half of the page, the wrong selection
would be made and, if `shift-i` was used to start inserting at the start
of the line, a single cursor would be placed at the cursor position
where the selection was started, instead of one cursor per each of the
selected lines.

These changes ensure that we now match Neovim's behavior for the same

Without this fix, the zed.dev server doesn't recognize the version with
metadata and redirects to /releases, which
defaults to the Stable channel, so Preview users end up seeing Stable
release notes.

Closes #47539

  Changes:
- Strip pre and build metadata from the semver version in
release_notes_url before constructing the path, so the URL
becomes /releases/preview/0.218.0 instead of
/releases/preview/0.218.0-beta.1+preview.131.68e98a53.
- Standardized the ordering of pre/build clearing to pre-first across
all 4 call sites (2 were build-first).



Open question: With this fix, the URL now points to the specific version
you're running (e.g.
/releases/preview/0.218.0). An alternative would be to link to
/releases/preview (no version) so users can see all
Preview releases, including ones newer than what they have installed. I
went with per-version linking since it matches
the existing intent of the code, but happy to change it if the team
prefers the other approach.

  Release Notes:

- Fixed "View Release Notes" in Preview/Stable opening the wrong release
channel page due to build metadata in the URL.

Closes #48256

It appears that the current git remotes support was implemented in
#42819, following the design described in
https://github.com/zed-industries/zed/pull/42486#issuecomment-3524092306.
That design does not include an interaction for deleting remotes, but
the delete remote branch action was mistakenly implemented as deleting
the remote itself.

After this PR, there should be no code paths that use `remove_remote`
anymore. I've kept it for now though, as it may be useful when we
introduce the corresponding interaction in the future.

Release Notes:

- Fixed a bug where deleting a remote branch from the branch picker
would incorrectly remove the entire remote configuration

solution for #43004

Release Notes:

- Added workspace::FocusCenterPane


The `editor::ToggleFocus` action not working really drives me bonkers,
and it also doesn't really make sense, because it doesn't toggle
anything. it moves focus, but doesn't move focus back anywhere if you
run it again so 'ToggleFocus' seems misleading.

Here we have added an action that just moves focus to the most recent
center pane: `workspace::FocusCenterPane`

this action correctly moves the focus to the center pane from any dock,
even if the center pane is the project diff, branch diff, terminal, or
keymap editor, etc.

i'm not sure if this would be considered a 'replacement' for
`editor::ToggleFocus` but i do think this is probably more in line with
what most users would consider the expected behavior.

This PR updates the pet dependency to incorporate performance
improvements from upstream.

- PR: microsoft/python-environment-tools#370

Updating pet reduces toolchain discovery time in WSL environments,
specifically when Conda is installed on the host Windows system. In my
testing, the time from clicking the toolchain button to the list
appearing was reduced by approximately 2 seconds.

While this is a notable improvement, discovery in WSL remains slightly
slower than in native development or remote Linux environments, where
toolchains are typically loaded near-instantaneously.

Before you mark this PR as ready for review, make sure that you have:
- [x] Added a solid test coverage and/or screenshots from doing manual
testing (no need)
- [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:

- Improved python toolchain discovery under WSL environment

With a large number of files in the git status, pressing stage/unstage
could cause a noticeable freeze. The async performance profiler showed
that the task spawned inside `change_all_files_stage` blocked the main
thread for 300ms+, resulting in a clear and visible UI stall. The main
cause was the need to traverse all entries to determine what to stage or
unstage, which becomes expensive for large change sets.

Same repro as: #47800

Release Notes:

- Improved latency of stage/unstage operations

https://clang.llvm.org/docs/StandardCPlusPlusModules.html#file-name-requirements,
`.cppm`, '.ccm', ".cxxm" files are C++20 module interface files.

Release Notes:

- Recognize module interface file as C++ file.
