Update `project::buffer_store::BufferStore.save_buffer_as` in order to
correctly update the `path_to_buffer_id` hash map, ensuring that the
currently open file's path is dissociated from the buffer's id, to
prevent the new buffer from being open when trying to open the original
file.

Closes #29783 

Release Notes:

- Fixed issue where using `workspace: save as` would prevent users from
opening the original file from which the new file was created

This PR removes the behavior that the number_field changes focus to the
previous element when using the decrement button.

I mainly noticed this while decreasing the tab-size of a language, since
it there closes the page...

Please note that I am unsure what if any purpose this code has.
I was unable to find a use case and since it is not present in the
`increment_handler` I guess it should never have been here

Release Notes:

* Fixed wrongly focus previous element on number_field decrement

The leak mainly showed up in the appearance page because it had a lot of
dropdown menus. The problem occurred because the drop-down menus were
creating a new entity on each frame instead of using the
`window.use_state...` API.

Current `Buffer` API only allows getting buffer text with `\n` line
breaks — even if the `\r\n` was used in the original file's text.

This it not correct in certain cases like LSP formatting, where language
servers need to have original document context for e.g. formatting
purposes.

Added new `Buffer` API, replaced all buffer LSP registration places with
the new one and added more tests.

Release Notes: 

- Fixed ESLint linebreak-style errors by preserving line endings in LSP
communication

Previously we had `Context` and `ContextStore` in both `agent_ui` (used
to store context for the inline assistant) and `assistant_context` (used
for text threads) which is confusing.
This PR makes it so that the `assistant_context` concepts are now called
`TextThread*`, the crate was renamed to `assistant_text_thread`

This PR does two related things:

- First, it gets rid of the undifferentiated `RepositoryEvent::Updated`
in favor of three new events that have clearer definitions:
`BranchChanged`, `StashEntriesChanged`, and `StatusesChanged`. An
implication of this is that we no longer emit a `RepositoryEvent` unless
some git state changed; previously we would emit `RepositoryUpdated`
after doing a git status scan even if no statuses changed.
- Second, it changes the subscription strategy of the project diff to
make it update more robustly. Previously, the project diff only
subscribed to the `GitStore`, so it relied on getting a `GitStoreEvent`
when some buffer's diff hunks changed, even if the git status of the
buffer's file didn't change (e.g. a second hunk in a file that was
already modified). After this PR, it also subscribes to the individual
`BufferDiff` entities for buffers that have a git status, so the
`GitStore` is freed from that responsibility. This also fixes some real
cases where the previous strategy was not effective in keeping the
project diff up to date (captured in a test).

Release Notes:

- Fixed some cases where the project diff would fail to update in
response to git events.

Release Notes:

- Fixed panic in copy highlight json action

This shrinks it from roughly a ~kilobyte to 8 byte, removing a bunch of
memmoves emitted by the compiler. Also `Arc`'s it instead of boxing as
we do clone it a couple times here and there, making that also a fair
bit cheaper

`wasmtime_wasi` might call into tokio futures (to sleep for example)
which requires access to the tokio runtime. So we are required to run
these extensions in the tokio thread pool

I also changed the debug picker to use a material list to cover the edge

Release Notes:

I made three significant changes in this PR. 

1. `SettingsWindow::fetch_files` now creates
`SettingsUiFile::Project(..)` for any worktree that contains no project
settings.
2. `update_settings_file` now creates an empty settings file if a
worktree doesn't contain one.
3. `open_current_settings_file` also creates a settings file if the
current one doesn't exist.

Release Notes:

- settings ui: Enable editing project settings for worktrees that don't
have a project setting file.

This PR gets the `SettingsWindow` struct to subscribe to all
`Entity<Project>` events and any future project entities that are
created. When a project emits an event that signals a worktree has been
added or removed, the settings window refetches all settings files it
can find.

This fixes a bug where the settings ui would notice some project
settings that were created or opened after the `SettingsWindow` has been
initialized.

I also renamed `LOCAL` file mask to `PROJECT` to be inline with the
`SettingsFile` naming convention.

Release Notes:

- settings ui: Fix bug where project setting files wouldn't be detected
if they were created or opened after while an active settings window is
open

Using `shlex` unconditionally is dangerous as it assumes the underlying
shell is POSIX which is not the case for PowerShell, CMD, or Nushell.
Therefore, whenever we want to quote the args we should utilise our
helper `util::shell::ShellKind::try_quote` which takes into account
which shell is being used to actually exec/spawn the invocation.

This is a refactoring PR to simplify our environment loading code by:

- Getting rid of `EnvironmentErrorMessage` in favor of using
`anyhow::Result` everywhere, with a separate `mpsc` channel to
communicate statuses that will be shown in the activity indicator
- Inlining some functions that were only called once to reduce
indirection
- Removing the separate `direnv` module

Release Notes:

Don't prepend the worktree root when using an absolute path from
`Worktree::which`, since that does the wrong thing when running in
wasmtime given two Windows absolute paths. Also don't pass this path to
`node`, since when npm installed it's a sh/cmd wrapper not a JS file.

Part of #39153, also needs a fix on the vscode-langservers-extracted
side (missing shebang for the vscode-html-language-server script).
