This PR updates the README of the `zed_extension_api` crate to show the
compatibility between different versions of `zed_extension_api` and Zed.

Due to peculiarities in handling of terminal panes (namely the fact that
they are not actually tracked by the Workspace::active_pane member), it
was possible to get into a state where status bar items "lost track" of
an active pane item; one way to reproduce it was to open a new terminal
via "workspace: new terminal" with a pane open in a central view; once a
new terminal is opened, the language selector and line number indicator
lose track of an active item. Focusing central view does nothing - it
will only go away after switching a tab in the central view.

To remedy this, we now always notify the status bar items of a pane
focus change, even if Workspace::active_pane points to the same pane.

Release Notes:

- Fixed status bar focus issues when spawning a terminal via `workspace:
new terminal` action.

This is another variant for this [original
PR](https://github.com/zed-industries/zed/pull/10091) to add settings to
show/hide navigation history buttons that puts the settings under a new
section called `tab_bar`:

```
  "tab_bar": {
    // Whether or not to show the navigation history buttons.
    "show_nav_history_buttons": true
  }
```

Fixes #4380

Parts im still unsure about:
- [x] where exactly I should call `on_lsp_start`/`on_lsp_end`
- [x] how to handle things better than `let is_references =
TypeId::of::<R>() == TypeId::of::<GetReferences>();`, which feels very
janky
- [x] I want to have the message be something like `"Finding references
to [...]"` instead of just `textDocument/references`, but I'm not sure
how to retrieve the name of the symbol that's being queried
- [ ] I think the bulk of the runtime is occupied by `let result =
language_server.request::<R::LspRequest>(lsp_params).await;`, but since
`ModelContext` isn't passed into it, I'm not sure how to update progress
from within that function
- [x] A good way to disambiguate between multiple calls to the same lsp
function; im currently using the function name itself as the unique
identifier for that request, which could create issues if multiple
`textDocument/references` requests are sent in parallel

Any help with these would be deeply appreciated!

Release Notes:

- Adds a status indicator for LSP actions

While working towards fixes for the image viewer, @mikayla-maki and I
discovered that we didn't have `object-fit: scale-down` implemented.
This doesn't _fully_ solve the image issues as there is some issue where
only the bounds width is updating on layout change that I haven't fully
chased down.

Release Notes:

- Fixed an incorrect reference to the `soft_wrap` setting in the default
settings documentation.

1. They now will not go off-screen
2. You can scroll long messages.
3. Only one notification per language server is shown at a time
4. The title/text are now distinguished visually
5. You can copy the error message to the clipboard

Fixes: #10217
Fixes: #10190

Release Notes:

- Fixed language server notifications being too large
([#10090](https://github.com/zed-industries/zed/issues/10090)).

We want Zed to be opinionated and low-configuration. Your code editor
should get out of the way, and just do the right thing.

However, some ecosystems aren't opinionated enough for us to
automatically detect the right way to format your code, so let's turn it
off.

Release Notes:

- Disabled `format_on_save` by default in C and C++.

@algora-pbc /claim #4273

This is a work-in-progress. The process for `gn` command is:

- maintain updated vim.workspace_state.search.initial_query
- modify editor.select_next_state with
vim.workspace_state.search.initial_query
- use editor.select_next()
- merge selections
- set editor.select_next_state to previous state

To make this possible, several private members and editor structures are
made public. `gN` is not yet implemented and the cursor still does not
jump to the next selection in the first use.

Maybe there is an better way to do this?

This PR adds the ability for extensions to implement
`language_server_workspace_configuration` to provide workspace
configuration to the language server.

We've used the Dart extension as a motivating example for this, pulling
it out into an extension in the process.

Release Notes:

- Removed built-in support for Dart, in favor of making it available as
an extension. The Dart extension will be suggested for download when you
open a `.dart` file.

This PR adds more documentation for various constructs in the
`zed_extension_api` crate.

`wit_bindgen` is able to generate doc comments on the Rust constructs
using the the doc comments in the WIT files, so we're able to leverage
that for the majority of the constructs that we expose.

This fixes #9786 by using an invocation of `/usr/bin/env` that's
supported by macOS 12.

As it turns out, on macOS 12 (and maybe 13?) `/usr/bin/env` doesn't
support the `-0` flag. In our case it would silently fail, since we
`exit 0` in our shell invocation and because the program we run and
whose exit code we check is the `$SHELL` and not `/usr/bin/env`.

What this change does is to drop the `-0` and instead split the
environment on `\n`. This works even if an environment variable contains
a newline character because that would then be escaped.

Release Notes:

- Fixed Zed not picking up shell environments correctly when running on
macOS 12. ([#9786](https://github.com/zed-industries/zed/issues/9786)).

Release notes:

- Fixed a crash when joining two consecutive lines
([#9692](https://github.com/zed-industries/zed/pull/9692)).


This crash is not caused by `vim` or `editor`'s code logic, `join_line`
logic is okay, I found that the crash is caused by a refresh of git
`diff` after every update, hhen git diff generates hunks, it will look
for the cursor to the beginning of a line, and judge that if the cursor
result column is greater than 0, that is, it is not the beginning of a
line, it will correct the row to the next line, I think before we forgot
here that I need to adjust the column to 0 at the same time, otherwise
it is easy to go out of bounds, I am not sure if I need to add more
tests for this method, I can add if I need to, but I feel that this case
is a bit extreme

#10080 introduced a minor change in how the min marker height is
enforced. Before the change, it was applied to the aggregated marker,
but after the change it's applied to each individual marker before
aggregation.

The difference is not noticeable on small files, where even single row
markers are higher than `MIN_MARKER_HEIGHT`, but it leads to visible
differences in large files with repeating blocks of highlighted and
not-highlighted blocks, like in [this
case](https://github.com/zed-industries/zed/pull/9080#issuecomment-2006796376).

This PR fixes how the `MIN_MARKER_HEIGHT` is applied.

When leaving a call/room in which a project was shared, the shared
project notification was not getting dismissed when the person that
shared the project left the room.
Although there was a `cx.emit(Event::Left)` call inside room, the event
was never received in the `project_shared_notification` module, because
the room is dropped before the event can be dispatched. Moving the
`cx.emit(Event::Left)` to the active call fixed the problem. Also
renamed `Event::Left` to `Event::RoomLeft` because the room join
equivalent is also called `Event::RoomJoined`.


Release Notes:

- Fixed project shared notification staying open, when the user that
shared the project left the room

When no formatter for a language is specified, Zed has the default
behaviour:

1. Attempt to format the buffer with `prettier`
2. If that doesn't work, use the language server.

The problem was that if `prettier` failed to format a buffer due to
legitimate syntax errors, we simply did a fallback to the language
server, which would then format over the syntax errors.

With JavaScript/React/TypeScript projects this could lead to a situation
where

1. Syntax error was introduced
2. Prettier fails
3. Zed ignores the error
4. typescript-language-server formats the buffer despite syntax errors

This would lead to some very weird formatting issues.

What this PR does is to fix the issue by handling `prettier` errors and
results in two user facing changes:

1. When no formatter is set (or set to `auto`) and if we attempted to
start a prettier instance to format, we will now display that error and
*not* fall back to language server formatting.
2. If the formatter is explicitly set to `prettier`, we will now show
errors if we failed to spawn prettier or failed to format with it.

This means that we now might show *more* errors than previously, but I
think that's better than not showing anything to the user at all.

And, of course, it also fixes the issue of invalid syntax being
formatted by the language server even though `prettier` failed with an
error.

Release Notes:

- Improved error handling when formatting buffers with `prettier`.
Previously `prettier` errors would be logged but ignored. Now `prettier`
errors are shown in the UI, just like language server errors when
formatting. And if no formatter is specified (or set to `"auto"`) and
Zed attempts to use `prettier` for formatting, then `prettier` errors
are no longer skipped. That fixes the issue of `prettier` not formatting
invalid syntax, but its error being skipped, leading to
`typescript-language-server` or another language server formatting
invalid syntax.

This commit introduces a new method `range` to calculate the target
range for selection expansion based on the current selection, movement
times, and other parameters. The `expand_selection` method is refactored
to use this new `range` method, simplifying the logic for expanding a
selection and making the code more modular and reusable. The `range`
method encapsulates the logic for calculating the new selection range,
including handling linewise selection and adjustments for surrounding
newlines, making it easier to understand and maintain the selection
expansion functionality.
