This PR makes it so the pending completion is cleared when an error
occurs.

This makes it so `Thread::is_streaming()` will return `false` in the
error case (and thus hide the streaming indicator in the UI).

Two issues i ran into while looking at the completion rating modal
- Single-file worktrees file names are not displayed at all
- Hard to see the filename when the path is long (lots of directories)

This PR fixes this by displaying the filename on the left, followed by
the full path (including the worktree name), similar to how we do it in
the file finder/assistant panel /file command

This fixes an error message that has shown up for me when joining collab
projects: "Unable to load shell environment in /<path on another
machine/"

Release Notes:

- Fixed error message about shell environment failing to load when
joining projects in collaboration.

Context pills are now focusable and intractable via the keyboard.

- <kbd>←</kbd> and <kbd>→</kbd> move the focus to the previous or next
item (wrapping if necessary)
- <kbd>↓</kbd> and <kbd>↑</kbd> move the focus vertically
- If the cursor is in the first/last row of the assistant/inline editor,
they will move the focus to the strip
- Inside the strip, they will move the focus to the pill horizontally
overlapping the most
- If already in the first/last row of the strip, they will move to the
first/last pill (like in editors)
- If the first/last pill is focused, they will move the focus back to
the editor
- <kbd>⌫</kbd>  removes the focused pill (unless it's the suggested one)
- <kbd>⏎</kbd> accepts the suggested pill if focused

This is a follow-up to #12640.
While profiling latency of working with a project with 8192 diagnostics
I've noticed that while we're parsing the LSP messages into a generic
message struct on a background thread, we can still block the main
thread as the conversion between that generic message struct and the
actual LSP message (for use by callback) is still happening on the main
thread.
This PR significantly constrains what a message callback can use, so
that it can be executed on any thread; we also send off message
conversion to the background thread. In practice new callback
constraints were already satisfied by all call sites, so no code outside
of the lsp crate had to be adjusted.

This has improved throughput of my 8192-benchmark from 40s to send out
all diagnostics after saving to ~20s. Now main thread is spending most
of the time updating our diagnostics sets, which can probably be
improved too.

Closes #ISSUE

Release Notes:

- Improved app responsiveness with huge # of diagnostics.

Follow-up of https://github.com/zed-industries/zed/pull/23112

Same reasoning applies.

Release Notes:

- Changed default formatter for C to be the primary language server, not
Prettier. Format-on-save is still disabled by default for C, but if one
uses the editor: format command now, it will default to the language
server. clangd can format C files, whereas prettier cannot.

As @hferreiro points out in [this

comment](https://github.com/zed-industries/zed/pull/18752#issuecomment-2589340565):
C++ and prettier don't work well together, so let's make the default
formatter for C++ the primary language server. We get that by disabling
prettier.

Release Notes:

- Changed default formatter for C++ to be the primary language server,
not Prettier. Format-on-save is still disabled by default for C++, but
if one uses the `editor: format` command now, it will default to the
language server. `clangd` can format C++ files, whereas prettier cannot.

Intended to include these in #23098, but seems they didn't push before
merge. Probably didn't use `--force-with-lease`

This PR is a follow-up to
https://github.com/zed-industries/zed/pull/22911 to further improve the
registration of code action providers for the Assistant in order to
prevent duplicates.

The `CodeActionProvider` trait now has an `id` method that is used to
return a unique ID for a code action provider. We use this to prevent
registering duplicates of the same provider.

The registration of the code action providers for Assistant1 and
Assistant2 have also been reworked. Previously we were not call the
registration function—and thus setting up the subscriptions—until we
resolved the feature flags. However, this could lead to the registration
happening too late for existing workspace items.

We now perform the registration right away and then remove the undesired
code action providers once the feature flags have been resolved.

This PR fixes an issue with jumping from multi_buffer to a file; namely,
the scroll offset of the opened buffer used to match the position within
the multibuffer, but it broke a while back. This is because we were
opening a buffer without providing the data about the origin scroll
offset.

Closes #ISSUE

Release Notes:

- Fixed a bug where the relative position of an excerpt within the
multibuffer was not accounted for while jumping to the buffer, causing
the clicked line to drastically change position on screen.

This PR removes some commented-out code from the codebase.

The new `ContextMenu`-based `ContextPicker` requires initialization when
opened, but we were only doing this for the `ContextStrip` picker, not
the inline one.

Additionally, because we have a wrapper element around ContextMenu, we
need to propagate the `DismissEvent` so that it properly closes when
Escape is pressed.

Release Notes:

Release Notes:

- Added configuration sent on initialization to the `Server Info`
section of the language server logs.

These comments are inaccurate. Even if `convert_case` provided a way to
customize which boundaries were used (which is now does, it 0.7.1), they
would be removed from the string and replaced with the new boundary
character (`-`, `_`, ...), and we'd lose the ability to reconstruct the
text the way the author formatted it. This is not a hack, this is the
way we have to do it.

This PR continues work on the feature flagged git panel.

Changes:
- Defines and wires up git panel actions & keybindings
- Re-scopes some actions from `git_ui` -> `git`.
- General git actions (StageAll, CommitChanges, ...) are scoped to
`git`.
- Git panel specific actions (Close, FocusCommitEditor, ...) are scoped
to `git_panel.
- Staging actions & UI are now connected to git!
- Unify more reusable git status into the GitState global over being
tied to the panel directly.
- Uses the new git status codepaths instead of filtering all workspace
entries

Closes #23006

This PR should have been split into two, but since the changes are
related, I merged them into one.

1. On load, the title bar actions and bottom bar toggles are
unresponsive until the center pane is clicked. This happens because the
terminal captures focus (even if it's closed) long after the workspace
sets focus to itself during loading.

The issue was in the `focus_view` call used in the `new` method of
`TerminalPanel`. Since new terminal views can be created behind the
scenes (i.e., without the terminal being visible to the user), we
shouldn't handle focus for the terminal in this case. Removing
`focus_view` from the `new` method has no impact on the existing
terminal focusing logic. I've tested scenarios such as creating new
terminals, splitting terminals, zooming, etc., and everything works as
expected.

2. Currently, on load, docked terminals do not automatically focus when
they are only visible item to the user. This PR implements it.

Before/After:

1. When only the dock terminal is visible on load. Terminal is focused.

2. When other items are visible along with the dock terminal on load.
Editor is focused.

3. Multiple tabs along with split panes. Last terminal is focused.

Future:

When a docked terminal is in a zoomed state and Zed is loaded, we should
prioritize focusing on the terminal over the active item (e.g., an
editor) behind it. This hasn't been implemented in this PR because the
zoomed state during the load function is stale. The correct state is
received later via the workspace. I'm still investigating where exactly
this should be handled, so this will be a separate PR.

cc: @SomeoneToIgnore 

Release Notes:

- Fixed unresponsive buttons on load until the center pane is clicked.  
- Added auto-focus for the docked terminal on load when no other item is
focused.

These keybindings extend the already selected text. This allows closer
emacs emulation where subsequent movement commands extend / shrink the
current selection instead of dismissing it.

This is a follow up on 
- #21927

Release Notes:

- Added emacs movement keybindings that extend/shrink the current
selection

Also:

* Adds `impl_internal_actions!` for deriving the `Action` trait without
registering.

* Removes some deserializers that immediately fail in favor of
`#[serde(skip)]` on fields where they were used. This also omits them
from the schema.

Release Notes:

- Keymap settings file now has more JSON schema information to inform
`json-language-server` completions and info, particularly for actions
that take input.

I added these notifies in #23011, but in practive have found them to be
overly disruptive. It would definitely be good to do something better
than logging here, but having a sticky error notification is worse. I
think it is still good to notify on mutation failures, so left those in

In particular with rust-analyzer, "Go to definition" and "Find
references" frequently fail with "Content modified" quite a while after
sending the request. Since users are probably used to these operations
being finicky it doesn't seem useful to have a prominent display of
errors for them.

Fixes terminal pane button opening two terminals on click.

The culprit is in

https://github.com/zed-industries/zed/blob/61115bd04792d87a540558753cd01a6368baba2a/crates/workspace/src/workspace.rs#L2412-L2417

* We cannot get any panel by index from the Dock, only an active one
* Both `dock.activate_panel(panel_index, cx);` and `dock.set_open(true,
cx);` do `active_panel.panel.set_active(true, cx);`

So, follow other pane's impls that have `active: bool` property for this
case, e.g.
https://github.com/zed-industries/zed/blob/3ec52d8451dd1178c4d036da3a71c827df422f4b/crates/assistant/src/inline_assistant.rs#L2687

This adds support for LSPs that use the old rename flow which does not
first ask the LSP for the rename range and check that it is a valid
range to rename.

capability to prepare renames - such as `luau-lsp`.
