When a subagent title is long, the header buttons (expand/collapse,
maximize, stop) were pushed out of view because the title area grew
unconstrained.

## Fix

- Add `min_w_0()` and `overflow_hidden()` to the title container so it
can shrink below its content width
- Add `truncate()` to the title label so it shows an ellipsis when
clipped
- Add `flex_shrink_0()` to the buttons container so it never gets
squeezed out
- Add a tooltip on the title area showing the full text on hover

This tackles another issue where we would incorrectly show two absolute
line numbers with relative line numbering enabled when it really should
only have been the current active line number.

Sadly, no tests rn for this as we would need a better test infra for
that to properly catch/test this bug. But with the refactored logic, I
think this is easier to understand at glance, so at least theres that

Release Notes:

- Fixed an issue with relative line numbers where some rows would be
missing their relative line number with deleted hunks showing.

## Summary

Fixes the `SyntaxError: Unexpected identifier 'gemini'` error in the
cherry-pick documentation suggestions workflow.

## Problem

The 'Post suggestions as PR comment' step was directly interpolating
markdown content into a JavaScript template literal:

```javascript
const suggestions = `${{ steps.analyze.outputs.suggestions }}`;
```

When the suggestions contained backticks, `${}` sequences, or other
special characters (like the `gemini-3.1-pro-preview` model name in
markdown code blocks), it broke the JavaScript syntax.

## Solution

Write suggestions to a file in `$RUNNER_TEMP` and read it using
`fs.readFileSync()` in the script step. This avoids all GitHub Actions
template interpolation and JavaScript string parsing issues.

## Testing

This should fix the failed run:
https://github.com/zed-industries/zed/actions/runs/22194396124/job/64190762087

Release Notes:

- N/A

Repro steps:

1. Make a Rust file and check it in to git
2. Delete a lot of the file
3. Expand all the diffs (cmd+")
4. Select larger syntax node (ctrl+cmd+right)
5. Collapse all the diffs
6. Select smaller syntax node (ctrl+cmd+left)
7. Panic!

The problem was we were using byte offsets instead of anchors so after
we shrank the buffer by collapsing diffs we'd be pointing past the end
of it.

## Summary

- Added Gemini 3.1 Pro to the pricing table, context windows table, and
page metadata in `docs/src/ai/models.md`
- Listed alongside existing Gemini 3 Pro (both remain available)

Release Notes:

- N/A

Closes AI-48

Release Notes:

- Added support for Gemini 3.1 Pro

Removes tool filtering since this was throwing off certain models, and
also allows for more generic task prompts that don't always require
summaries. Since the models usually provide a wrap-up message, we don't
have to wait for another turn.

This also sets us up to allow the agent to re-interact with an existing
subagent thread.

* Update the font weight used in the Agent Panel's editor to respect the
`buffer_font_weight` setting.
* Update the font weight used in the Command Palette to use the
`ui_font_weight` setting value, seeing as the command palette is using
the `ui_font` settings for the font family and features
* Update the font weight used in the popovers to match the
`buffer_font_weight`, as it's also using the buffer font family and
features
* Update the `LabelLike.buffer_font` method in order to correctly set
the font weight, which fixes the font weight used in the file header
when displaying a multibuffer editor

Release Notes:

- Fixed incorrect font weight in the Command Pallete input
- Fixed missing font weight the Agent Panel's buffer
- Fixed missing font weight the Hover Popover
- Fixed missing font weight in Markdown's code block and inline code

This PR adds the `AnnouncementToast` component that we can use whenever
a new version introduces a new and special feature that's worthy of a
flashier announcement. We can pick the specific version we want to
target, and instead of showing the regular "View Release Notes" toast,
we'd show this new one instead.

For now, everything is turned off as we're not sure yet which version we
will be targeting for an upcoming release.

Ensure that editing one tag in a linked pair correctly mirrors the change 
to the other tag for Vim delete/change/substitute commands, visual 
mode operations, and the standard editor delete action.

Extract a `LinkedEdits` struct to deduplicate linked edit collection and
application across `handle_input`, `replace_selections`, `do_completion`,
`backspace`, and `delete`. Introduce `linked_edits_for_selections` as a
shared helper for building linked edits from the current selections.

Closes #35941

Release Notes:
- Fixed linked edits for delete/change/substitute commands so tag pairs
stay in sync.

Fixes the workflow failure where `gh auth login --with-token` fails
because `GH_TOKEN` is already set in the environment.

The error was:
```
The value of the GH_TOKEN environment variable is being used for authentication.
To have GitHub CLI store credentials instead, first clear the value from the environment.
```

The fix uses a subshell to unset `GH_TOKEN` before calling `gh auth
login`:
```bash
echo "$GH_TOKEN" | (unset GH_TOKEN && gh auth login --with-token)
```

The OpenFiles action was always using the system file picker dialog,
ignoring the use_system_path_prompts setting. This adds a
workspace-level handler that calls prompt_for_open_path, which respects
the setting, instead of falling through to the global handler.

Closes #46386

- Fixed "workspace: open files" not respecting "use_system_path_prompts"

When clipboard data was produced by the editor's copy/cut with multiple
entire-line selections, vim's paste would panic with `byte index N is
out of bounds`.

The editor's `do_copy` and `cut_common` skip the `\n` separator between
clipboard selections when the previous selection was an entire-line
selection (because the text already ends with `\n`). However, vim's
paste code unconditionally did `start_offset = end_offset + 1`, always
assuming a `\n` separator exists between every pair of selections. This
caused the accumulated offset to exceed the text length, resulting in a
string slicing panic.

The fix checks `clipboard_selection.is_entire_line` to decide whether to
skip the separator, matching the behavior of the editor's own `do_paste`
method. The same fix is applied to both the vim and helix paste
implementations.

Release Notes:

- Fixed a crash when using vim paste on clipboard data copied with the
editor's copy command containing multiple entire-line selections.

This PR removes the `AccessToken` database model and its related

This PR updates Collab to make it validate access tokens through Cloud
instead of doing it in-house.

We're reusing the `GET /client/users/me` endpoint—which is what we also
call on the client—to validate the user's access token.

We only need to do this when establishing a WebSocket connection, so the
increased latency of a network hop shouldn't be a problem.

Closes CLO-308.

Fix git auth conflict in background_agent_mvp workflow

The workflow was manually configuring git authentication with:
```bash
git config --local http.https://github.com/.extraheader "AUTHORIZATION: bearer ..."
```

This conflicted with the authentication already set up by
`actions/checkout@v4`, which uses `AUTHORIZATION: basic ...`.

The conflict caused all crash pipeline runs to fail with:
```
fatal: could not read Username for 'https://github.com'
```

This morning's run (22147984206) failed for all 15 crash candidates
(ZED-4VS, ZED-202, etc.) with this error.

Remove the redundant git config since actions/checkout already handles
authentication properly.

Fixes two issues in the documentation suggestions workflow:

1. **Shell quoting bug**: PR titles containing quotes (e.g., `agent_ui:
Add the ability to undo "reject all"`) were breaking the shell script
because the title was substituted directly into the script. Moved
`PR_TITLE`, `PR_NUM`, and `OUTPUT_FILE` to environment variables where
special characters are handled safely.

2. **GH CLI auth issue**: The `gh` CLI sometimes fails to auto-detect
`GH_TOKEN` in the environment, causing `gh pr view` and `gh pr diff` to
fail with "Bad credentials". Added explicit `gh auth login --with-token`
in both the batch-suggestions and cherry-pick-suggestions jobs.

Release Notes:

Add `agent_worktree_directory` to `GitSettings` for configuring where
agent worktrees are stored (default: Zed data dir). Remove `Copy` derive
from `GitSettings`/`GitContentSettings` (incompatible with String field)

Define `AgentGitWorktreeInfo` (branch, worktree_path, base_ref) and add
it to `DbThread` + `DbThreadMetadata` for persistence and session list
display.
