This PR fixes the language model selector.

I tried to piece together the state prior to #25697 (the state it was in
at 11838cf89e0b96531f90f22432b3df6859587871) while retaining unrelated
changes that happened since then.

Release Notes:

- Fixed an issue where language models would not be authenticated until
after the model selector was opened (Preview only).

This fixes a performance problem introduced in #25906 and caused by
calling `BufferDiff::snapshot` too frequently.

Release Notes:

- Fixed a performance regression related to buffer diffs

Renamed the `vim::Backspace` and `vim::Space` actions to
`vim::WrappingLeft` and `vim::WrappingRight` respectively. The old names
are still available, but they are marked as deprecated and users are
advised to use the new names.

Also added a paragraph to the docs describing how to enable wrapping
cursor navigation.

Nushell does not support `uname -sm`
So invoke `sh -c "uname -sm"` instead which will also work under nushell.
See https://github.com/nushell/nushell/issues/12570 for the choice quote: "being posix/bash compliant is a non-goal"

Release Notes:

- Fixed ssh remotes running Nushell

These changes tackle two issues with running terminal commands via vim
mode:

- When using `!!` the tab's title was set to `!!` instead of the
previous command that was run and these changes fix that in order to
always display the previous command in the tab's title when re-running
the command with `!!`
- For a terminal command, pressing the rerun button would actually bring
up the task palette, so this has been updated in order to disable the
rerun button when the terminal tab was spawned via a vim command

Closes #25800 

Release Notes:

- Fixed the terminal tab title when using `!!` to rerun the last command
- Improved the terminal tab for when command is run via vim mode, in
order to disable the rerun button, seeing as Zed does not support it

Closes #25647

This PR fixes two issues related to cmd + click on URL:

1. Normally cmd + click on URL, it opens browser. Now, alt + tab back to
Zed. If you cmd + click on link again it won't work, until you normal
click some where else in buffer. It won't even show underline.

2. Again, cmd + click on URL, it opens browser. Now, alt + tab back to
Zed. If you cmd + click, some where else in buffer like just normal
text, and now try to hover on URL it won't show up underline and cmd +
click on it won't work. Unless again, if you plain click somewhere else.

Problem:

Issue is when clicking we set pending anchor (for selection), and when
we mouse up we clear those. This works for normal case without pressing
any modifier.

But, in case of cmd modifier, we set pending anchor (set when
`SelectPhase::Begin`), but we don't clear it once we use that data.

Fix: 

Once we end up using selection, anchor, etc data to figure out where to
navigate either URL/defination etc, we clear selection just like how we
do it in normal click. This doesn't require to happen after navigate
task, so we do it right after our usage of it.

Closes #21974

`resolve_path_in_worktrees` function looks for provided path in each
worktree until valid file is found.

In this PR we priortize current buffer worktree before other worktrees,
because of edge case where, file with same name might exists in other
worktrees.

Updated tests to handle this case.

Release Notes:

- Fixed an issue where the wrong file from a different worktree would
open when using `Cmd + Click` on a file import.

Changes:

Release Notes:

- vim: Added support for toggling boolean values with `ctrl-a`/`ctrl-x`

Fixes two issues with the Vim exchange implementation:

1. The clear exchange implementation **didn't** clear the exchange. This
was due to us asking the editor to clear normal highlights instead of
background highlights.
2. Calling clear exchange also wouldn't cause the operator to be
cleared, so you would be left in operator = "cx".

I've added tests for both of these cases.

Partially closes #25750. It doesn't address the problem with dot repeat
not working for my custom bindings, but I don't know what would cause
that. I'd love to hear some thoughts on why that is. That might be a
problem on my part or it might be something with the code. Input would
be appreciated.

Release Notes:

- Fixed: Vim exchange's "clear exchange" function didn't clear the
exchange and kept you in operator pending mode.

This solves a couple of issues with Vim search by making the search
buffer and `SearchableItem` aware of the direction of the search. If
`SearchOptions::BACKWARDS` is set, all operations will be reversed. By
making `SearchableItem` aware of the direction, the correct active match
can be selected when searching backward.

Fixes #22506. This PR does not fix the last problem in that issue, but
that one is also tracked in #8049.

- Fixes incorrect behavior of backward search in Vim mode

Proper version of https://github.com/zed-industries/zed/pull/25425
When https://github.com/zed-industries/zed/pull/24857 returned font
updates on settings changes, settings values, not in-memory ones should
be compared.

This PR returns back the logic finally, and changes it to explicitly
track the settings values, not the in-memory ones.
Also adds the same tracking for UI font changes, which had never been
tracked before.

Release Notes:

- Fixed font sizes not reacting on settings change

This PR adds the `git.hunk_style` setting, allowing setting an alternate
style for hunks – specifically the rendering of unstaged hunks.

It has 2 options:

- `transparent` (unstaged hunks are more transparent/less opaque than
staged hunks)
- `pattern (unstaged hunks are indicated by a visual pattern)

We'll possibly explore a VSCode-style "don't show staged hunks", but the
complexity it adds is a bit out of scope for now.

Closes #22999 
# Problem

Currently, the default soft wrap mode of an editor is determined by
reading the language-specific settings of the language _at offset zero_
in the editor's (multi)buffer. While this provides a way to pick a
single soft wrap mode for a multi-language multibuffer, it's a bad
choice for a single-buffer multibuffer that begins with a different
embedded language. For example, Markdown with frontmatter:

```markdown
---
my_front_matter
---

# Hello World
```

Setting this in config:

```json
  "languages": {
    "Markdown": { "soft_wrap": "bounded" }
  },
```

Will not soft wrap the Markdown file as the language at offset zero is
YAML.

# Solution

Instead of using the language at offset zero, use the language of the
first buffer in the multibuffer (the buffer at offset zero). This gives
better behavior for single-buffer editors, and a similar default for
multi-language multibuffers as before.

# Testing

All existing `editor` crate tests pass, but I would appreciate any
guidance for where best to add additional testing.

Release Notes:

- Fixed soft_wrap setting not applying to buffers starting with a
different language

Release Notes:

- N/A

If the user already binds `tab`/`alt-tab`/`alt-l` to a different action
in a conflicting context and hasn't assigned a different keybinding for
`editor::AcceptEditPrediction`, we would show broken popovers with no

Instead, they will now see an error-variant of every popover which
includes a tooltip with a short description and buttons to open the
keymap, and open a new docs section explaining the issue in detail and
how to fix it.

We modified few actions in
https://github.com/zed-industries/zed/pull/25846, which are:

`"editor::GoToHunk" -> ["editor::GoToHunk", { "center_cursor": true }]`
`"editor::GoToPrevHunk" -> ["editor::GoToPrevHunk", { "center_cursor":
true }]`

Also, recently we changed and added migration for:

`["editor::GoToPrevHunk", { "center_cursor": true }] ->
["editor::GoToPreviousHunk", { "center_cursor": true }] `

This means:

1. User that might still have `editor::GoToHunk` won't be automatically
migrated to `["editor::GoToHunk", { "center_cursor": true }]`. Note
value of `center_cursor` is false, in first case (default), and true in
second case.

2. User that might still have `editor::GoToPrevHunk` won't be
automatically migrated to `["editor::GoToPreviousHunk", {
"center_cursor": true }]`. Note, `editor::GoToPrevHunk` is renamed
since, it is now invalid action.

This PR adds those migrations.

Closes #22447

When navigate forward/back, the focus moves from the ProjectSearchView's
result editor to the Pane, and then move to the ProjectSearchView, but
the event `on_focus_in` not triggered for ProjectSearchView, causing the
result editor to lose focus eventually.


https://github.com/zed-industries/zed/blob/f6dabadaf79bd29c89c8d55a1e9f1d33236f736e/crates/workspace/src/workspace.rs#L1372

Considering that the navigation might be triggered again in the next
frame, so use `on_next_frame` in `on_focus` event to move focus to
result editor.

Next frame:
- the blur event triggered for result editor.
- focus move from ProjectSearchView to result editor in `on_focus` event
for ProjectSearchView
- navigate again, focus moves from result editor to Pane then move back
to ProjectSearchView
- the focus not change during this frame, so no focus event happened for
ProjectSearchView.

Release Notes:

Fixes #16057

In newer versions of clangd, the switch labelDetailsSupport in the json
passed to the language server modifies the format of the returned json.
Zed handles well the old format, but misses the function parameters in
the new one. For example:
The old format looks like this:
```json
...
"label": " Window(int width, int height, const char *name, bool vsync, bool resizable)",
...
```
and with labelDetailsSupport = true:
```json
...
 "label": " Window",
 "labelDetails": {
     "detail": "(int width, int height, const char *name, bool vsync, bool resizable)"
 },
...
```
A simple solution is to just to not tell the language server that label
details are supported and force it to use the old format. This is a
dirty fix, but makes the completions behave like in the old versions of
clangd.

I do not know if this will break another language server. From what I've
found out most lsp-s do not depend on that setting and provide all
completion data either way. If not, this switch will need to be exposed
in a config or be at least lsp-dependant.

Lastly, I do not know Rust, maybe will need help to make a better fix
for the issue.

Release Notes:

- Fixed broken C++ completion suggestions

Closes #25885 

This PR improves the matching for file icons to tabs. 
Previously, the tab icon would be resolved based upon the relative path
in the current project. However, this caused the default file icon being
assigned to all files outside of the project, as the relative path for
these files would be empty.

Instead, `path_for_buffer` is now used which always returns a proper
file name even for paths outside the current project (as also stated [in
this
comment](https://github.com/zed-industries/zed/blob/fee9c677078ad5beebe151e8350e1fc353230dc9/crates/editor/src/items.rs#L1689)).
As the file name is sufficient for matching icons to files, this fixes
the linked issue whilst not changing anything for previously properly
matched icons.
