### Why?

Small nit I noticed when configuring `ty` from Zed docs, ty should
always be stylized as lowercase.

This makes this take the LSP adapter delegate instead of the binary
itself.

Despite us passing `LanguageServerBinaryOptions` with `allow_download:
false`, extensions would still try to download the binary because it was
never implemented for these to respect that. This would cause us to try
to download all langauge servers provided by extensions when opening a
settings file and/or requesting the JSON schema for that.

This PR fixes this by passing the LSP adapter delegate instead, so the
few language servers which actually want to have the binary for
resolving the initialization options can decide on this by themselves.
With that, we no longer download all language servers for the schema
request

This PR reworks the (still feature-gated) side-by-side diff view to use
a different approach to representing the multibuffers on the left- and
right-hand sides.

Previously, these two multibuffers used identical sets of buffers and
excerpts, and were made to behave differently by adding a new knob to
the multibuffer controlling how diffs are displayed. Specifically, the
left-hand side multibuffer would filter out the added range of each hunk
from the excerpts using a new `FilteredInsertedHunk` diff transform, and
the right-hand side would simply not show the deleted sides of expanded
hunks. This approach has some problems:

- Line numbers, and actions that navigate by line number, behaved
incorrectly for the left-hand side.
- Syntax highlighting and other features that use the buffer syntax tree
also behaved incorrectly for the left-hand side.

In this PR, we've switched to using independent buffers to build the
left-hand side. These buffers are constructed using the base texts for
the corresponding diffs, and their lifecycle is managed by `BufferDiff`.
The red "deleted" regions on the left-hand side are represented by
`BufferContent` diff transforms, not `DeletedHunk` transforms. This
means each excerpt on the left represents a contiguous slice of a single
buffer, which fixes the above issues by construction.

The tradeoff with this new approach is that we now have to manually
synchronize excerpt ranges from the right side to the left, which we do
using `BufferDiffSnapshot::row_to_base_text_row`.

This ensures that all sub-processes that were launched by the ACP server
are terminated. One scenario where this is easily reproducible:
- Start a new Claude Code ACP session
- Submit a prompt
- While Claude-code is still responding, start a new session
- The `claude-code` subprocess is leaked from the previous session (The
Claude-code SDK runs the Claude-code binary in a sub process)

This PR fixes this by using process groups on Unix. 
It does not fix the process leaks on Windows yet (will follow up with
another PR)

Release Notes:

- Fixed an issue where subprocesses of ACP servers could be leaked after
starting a new session

The existing link was 404-ing as the crate was renamed.

This has been something we've wanted to do for a long time since docs
aside thus far have been hard-anchored either at the top or bottom of
the container that their trigger is sitting in. This PR introduces the
change so that they're centered with their trigger, regardless of
whether it's on a context menu or picker, by including a canvas element
in both the container and the trigger to calculate where the docs aside
should precisely sit on. Here's the result:


https://github.com/user-attachments/assets/8147ad05-1927-4353-991d-405631de67d0

Note that at the moment, docs aside are only visible through _hovering_,
and ideally, they should be available on both hover and selection
(keyboard nav). But I'll leave that for later.

Closes https://github.com/zed-industries/zed/issues/45630

Remote host location alone is not enough to distinguish between remote
worktrees: different remote projects open in different windows will have
the same remote host location and _will_ have the same `WorktreeId`.

Thus, require an associated `WorktreeStore` with all
`WorktreeId`-related trust questions, and store those IDs based on the
store key.

Release Notes:

- Fixed worktree trust handling of multiple projects on the same remote
host

This makes the rollout as well as distinguishing this in the future

There were several places adding a copy icon button, so thought of
encapsulating the logic to copy a given string into the clipboard (and
other small details like swapping the icon and tooltip if copied) into a
component, making it easier to introduce this sort of functionality in
the future, with fewer lines of code.

All it takes (for the simplest case) is:

```rs
CopyButton::new(your_message)
```

Thanks for the cool project and making it open source! Started using Zed
recently and I really enjoy it.

Made a tiny addition to devcontainer docs to specify the version. Wasn't
able to get it to work as shown in the
[docs](https://zed.dev/docs/dev-containers) (should "just work"). The
feature was introduced recently on [PR
44442](https://github.com/zed-industries/zed/pull/44442) and is only
available as of v0.218 (currently still in preview), while I was still
on the latest stable version.

So I thought of opening a small PR 😊 

Thanks again for the awesome project!

This PR introduces the `MentionCrease` component, aimed at solving two
issues with mention creases in the agent panel:
- Previously, the mention crease was using a button with a regular size,
which is bigger than the default buffer font line height. That made the
crease look clipped and also overlapping with one another when in a
multiple line scenario where the creases would be on top of each other.
`MentionCrease` uses the window line height value to set the button
height, with a small one pixel vertical padding just for a bit of
spacing.
- Previously, given the crease used a `Label`, its font size wouldn't
scale if you changed the `agent_buffer_font_size` setting. Now,
`MentionCrease` uses that font size value, which makes regular text and
its text grow together as you'd expect.

Release Notes:

- agent: Fix a bug where mention creases didn't scale with
`agent_buffer_font_size` and got clipped/jumbled when rendered one above
the other.

Release Notes:

- Use the files name for "is svg" checks so SVG previews and the toolbar
button work in single-file mode.

Initial investigation and Zed memory trace:
https://github.com/zed-industries/zed/issues/42845#issuecomment-3687877977

The PR consists of 2 commits:
*
[first](https://github.com/zed-industries/zed/pull/45669/changes/732d308c8d7e9af3649ac71ea65a9c029af820fc)
adds cosmetic fixes to remove backtraces from logs yet again and print
paths in quotes, as file descriptors may return empty paths.
It also stubs the cause if OOM in project panel: that one traversed all
worktrees in `for worktree_snapshot in visible_worktrees` and "accepted"
the one with empty paths + never called `entry_iter.advance();` in "no
file name found for the worktree" case, thus looping endlessly and
bloating the memory quite fast.

*
[second](https://github.com/zed-industries/zed/pull/45669/changes/7ebfe5da2fc6d32f3fa2d71c761f8b2ec26d945b)
adds something that resembles a fix: `fn current_path` on macOS used the
file handler to re-fetch the worktree root file path on worktree root
canonicalization failure.
What's odd, is that `libc::fcntl` returns `0` in the case when external
volume is not mounted, thus resulting in the `""` path string that is
propagated all the way up.

*
[third](https://github.com/zed-industries/zed/pull/45669/changes/1a7560cef3e9fac604124c19f46b1f9c7b91815f)
moves the fix down to the platform-related FS implementations

The "fix" now checks the only usage of this method inside `async fn
process_events` for an empty path and bails if that is the case.
I am not sure what is a better fix, but this stops any memory leaks and
given how bad the situation now, seems ok to merge for now with the
`TODO` comment for more clever people to fix properly later.

----------------

Now, when I disconnect the SMB share and reconnect it again, Zed stops
displaying any files in the project tree but the ones opened as editors.

As before, at first, when the share is unmounted, Zed fails to save any
changes because of the timeouts.

Later, when the share is re-connected, macOS Finder hangs still but Zed
starts to react on saves yet still only shows the files that are open as
editors.
The files can be edited and saved from now on.

Later, when Finder finally stops hanging and indicates that the share is
mounted fully, the rest of the file structure reappear in the project
panel, and all file saves are propagated, hence can be observed in the
share in Finder.

It feels that one good improvement to add on top is some "disconnected"
indicator that clearly shows that the file is not properly handles in
the OS.
This requires much more changes and thinking as nothing like that exists
in Zed yet, hence not done.

Release Notes:

- Fixed Zed OOM-ing when macOS file descriptors become invalid

Follow up to https://github.com/zed-industries/zed/pull/45311. Instead
of searching for the string in the find pasteboard as soon as the pane
is focused, we will now wait until the search bar is either deployed or
`Select{Next|Prev}Match` is triggered.

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.

### Three code paths

1. **Offscreen** (`intersection.size <= 0`): Early exit, process 0 cells
2. **Fully visible** (`intersection == bounds`): Fast path, stream cells
directly (no allocation)
3. **Partially clipped**: Group cells by line, skip/take visible rows
only

### Key insight: filter by screen position, not buffer coordinates

The previous approach tried to filter cells by `cell.point.line`
(terminal buffer coordinates), which breaks in Scrollable mode where
cells can have negative line numbers for scrollback history.

The new approach filters by **screen position** using
`chunk_by(line).skip(N).take(M)`, which works regardless of the actual
line numbers because we're filtering on enumerated line group index.

## Testing

Added comprehensive unit tests for:
- Screen-position filtering with positive lines (Inline mode)
- Screen-position filtering with negative lines (Scrollable mode with
scrollback)
- Edge cases (skip all, positioning math)
- Unified filtering works for both modes

Manually verified:
- Terminal fully visible (no clipping) ✓
- Terminal clipped from top/bottom ✓
- Terminal completely outside viewport ✓
- Scrollable terminals with scrollback history ✓
- Selection/interaction still works ✓

Release Notes:

- Improved Agent Panel performance when terminals are scrolled
offscreen.
