Remove the changes introduced in the previous commit and update the
`MessageEditor.confirm_mention_for_selection` method in order to request
autoscroll from the editor twice, one of them delayed, as this appears
to fix the scrolling issue, regardless of the number of cursors used.

I'm not yet entirely sure why this is the case, so further investigation
is probably warranted in order to actually understand if this is the
best fix we can do right now, and why.

Replace O(n²) linear search with O(log n) binary search for checking
selection overlaps when finding next selection range. Pre-sort selection
ranges and use binary search to significantly improve performance when
working with many selections.

Due to using anyhow here, we otherwise lose the relevant error and just
surface a fairly useless error message.

Intentionally not doing this for `extension.json` parsing since that is
deprecated.

This makes it easier to see the image bounds for images with transparent
backgrounds.

src="https://github.com/user-attachments/assets/e1555576-39a2-4240-b9d3-67574df76f0d"
/>

Release Notes:

- Updated image preview background checkboxes to match the actual image
size, making it easier to see the bounds of images with transparent
backgrounds.

Currently when extending a selection using shift-click, the selection
granularity (or `SelectMode`) is based on the click count when extending
the selection, not on the click count of the initial selection. For
example, selecting a word with double-click followed by shift-click uses
a character granularity:


https://github.com/user-attachments/assets/13c78bb9-9c31-45d4-97de-99c30c7425a7

This PR changes this behavior to be more in line with other editors that
I'm familiar with by preserving the granularity of the initial selection
(unless the extension has a higher click count, i.e. the behavior of a
single click selection by a shift-double-click extension is unchanged):


https://github.com/user-attachments/assets/92e69e95-7ea2-4f76-b0a4-e4b9efa1947b

Release Notes:

- Extending a selection using shift-click now preserves the
character/word/line granularity of the initial selection

It looks like a `.is_local()` check got left in from the original
debugger implementation. I was able to view remote logs just fine after
removing it.

Release Notes:

- Fixed DAP logs being unviewable on remote projects.

Repro:
- Open a multibuffer
- Click on a line number to jump to the corresponding file
- Click the back button
- Click the forward button, nothing happens
- Click the forward button again, now it works

Double clicking the code to jump to the file (with
`"double_click_in_multibuffer": "open"`) doesn't exhibit this bug, so I
just changed the logic when clicking on a line number in a multibuffer
to match that behavior.

Closes #39974

Since the thumb hitboxes themselves do not propagate events, we need to
paint the normal parent hitbox on top of the other ones. This also
caused hover detection to fail, which caused the issue linked.

Release Notes:

- Fixed an issue where hovering scrollbars in hovers would dismiss
these.

Hi! In https://github.com/zed-extensions/ruby/issues/162 we renamed
embedded template languages:

- `HTML/ERB` to `HTML+ERB`
- `YAML/ERB` to `YAML+ERB`
- `JS/ERB` to `JS+ERB`

This pull request updates the Ruby extension documentation to reflect
that change. Thanks!

it appears that the vscode-css-languageservice is used so I think this

The previous code clones all the rope chunks, but the rope is passed by
value so the chunks are about to be dropped anyhow.

I thought this may slightly help performance but it has no very
noticeable effect, with a mix of small changes up and down probably
attributable to noise on my machine?

I wonder if the benchmarks might just not hit this path well? I'm
looking into that separately (see #39949, #39951), but this seemed clear
enough to be worth proposing by itself.

Incidentally it surprised me this did not generate a warning already,
but I think it's because we're taking only one field from the struct
that's about to be dropped:

Follow up to https://github.com/zed-industries/zed/pull/39979. The
previous PR made it the title would change even if you were on a
non-root tree view item. This PR fixes that by fixating the title to
show only the root tree view item.

Closes #ISSUE

Release Notes:

- settings: Deprecated `code_actions_on_format` in favor of specifying
code actions to run on format inline in the `formatter` array.

Previously, you would configure code actions to run on format like this:

```json
{
  "code_actions_on_format": {
    "source.organizeImports": true,
    "source.fixAll.eslint": true
  }
}
```

This has been migrated to the new format:

```json
{
  "formatter": [
    {
      "code_action": "source.organizeImports"
    },
    {
      "code_action": "source.fixAll.eslint"
    }
  ]
}
```

This change will be automatically migrated for you. If you had an
existing `formatter` setting, the code actions are prepended to your
formatter array (matching the existing behavior). This migration applies
to both global settings and language-specific settings

Before (broken behavior):

The child element resets its parent and siblings' opacity, which is an
unexpected behavior.

After (fixed behavior):

Release Notes:

- Fixed an issue where nested opacity is rendered incorrectly.

This PR renames the following actions to make it easier and prioritize
the UI version of interacting with them:

| Before | After |
|--------|--------|
| `OpenSettingsEditor` | `OpenSettings` |
| `OpenSettings` | `OpenSettingsFile` |
| `OpenKeymapEditor` | `OpenKeymap` |
| `OpenKeymap` | `OpenKeymapFile` | 

Release Notes:

- Rename actions to open settings (UI/window and JSON file) as well as
to open the keymap (editor tab and JSON file).

This fixes an issue introduced via
[v0.208.0-pre](https://github.com/zed-industries/zed/releases/tag/v0.208.0-pre)
and reported via
https://github.com/zed-industries/zed/issues/34530#issuecomment-3386042577
where, when using fish shell as the default shell and using a Claude
Code thread in Zed, all command were failing because `(command)` in fish
is for command substitution. Using it creates this type of error:

```
fish: command substitutions not allowed in command position. Try var=(your-cmd) $var ...
(npm ci) </dev/null
^~~~~~~~~~~~^
```

or in the editor itself:

/>


Using the appropriate syntax to redirect to stdin for fish fixes the
issue.

Release Notes:

- Fixed redirect stdin command for fish shell

Previously we were always adding a `Navigable` entry for the "new WSL
connection" option in this modal, even though we don't have the
corresponding button on non-Windows. This was causing `menu::SelectNext`
to behave incorrectly (focusing the center pane instead) when `Connect
New Server` was selected on macOS and Linux.

Release Notes:

- Fixed a bug with keyboard navigation in the remote project modal.

whichever GPU is currently connected. This is a much simpler solution
than the one I have here
(https://github.com/zed-industries/zed/pull/39264 - updated) and while
I'm sure I could imagine someone wanting to choose their GPU to render
Zed on, that may not be something that the application really needs to
support.

Gathering LSP declarations in zeta_cli can take a really long time for
big repos and has to be started from scratch if interrupted.

Instead of writing the cache file once we have walked the whole
worktree, we'll now do so incrementally as we complete each file. On
subsequent runs, we'll load as many valid declarations as has been
previously written to the cache, and then continue to request the rest
from the LSP which will append to the existing file as it makes
progress. If the last cache entry is incomplete, we'll truncate the
cache file to the end of the last valid line and continue from there, so
we can just `ctrl-c` without breaking resumability.

Release Notes:

- N/A

- Update `AcpThreadView.insert_selections` to take into account whether
the user is currently editing an existing message and, if it is, insert
the selection into that message instead of the thread's message editor
- Update Window's default keymap to use the `agent::QuoteSelection`
action instead of the deprecated `assistant::QuoteSelection` action
- Introduce `AcpThreadView.active_editor` to allow callers to retrieve
either the thread view's message editor or the editor for the message
being edited, in case `AcpThreadView.editing_message` is not `None`
- Improve `AcpThreadView.focus_handle` to focus on the message being
currently edited in case the user navigates back to the editor and then
to the thread view again, all while editing a message
- Add tests for `AcpThreadView.insert_selections`, ensuring that the
selection is inserted in the message being currently edited, if a
message is being edited, or the thread view's message editor if no
message is being edited

Closes #39693 

Release Notes:

- Improved `agent: quote selection` to also work for a message that was
already sent but is being edited

The feedback modal did not match our keyboard-driven design. We can
revisit this later if we want, but for now, removing it makes sense. All
actions have been inlined in the `Help` menu to maintain
discoverability.

Additionally, not all feedback-based actions in the command palette were
namespaced under `feedback:`, and now they are, so they can all be found
there easily.

Release Notes:

- Notice: The `Give Feedback` modal has been removed. The options to
file bug reports, feature requests, email us, and open the Zed
repository can now be found within the `Help` menu directly. The command
palette actions have undergone the following changes:

- `feedback: give feedback` (removed)
- `feedback: file bug report` (no change)
- `zed: request feature` → `feedback: request feature`
- `zed: email zed` → `feedback: email zed`
- `zed: open zed repo` → `contribute: open zed repo`
