Closes https://github.com/zed-industries/zed/issues/9458

When flying in a plane being totally offline, I've discovered that my
Rust projects do not have any LSP support and rust-analyzer disappeared
out of `~/Library/Application Support/Zed/languages/rust-analyzer/`
directory.

Looking at the
[bad.log](https://github.com/zed-industries/zed/files/14627508/bad.log),
it appears that `get_language_server_command` tries to find a newer LSP
server version and fails on
https://github.com/zed-industries/zed/blob/80bc6c8cc800e23ba79723b0c46b731a62203224/crates/language/src/language.rs#L339

bailing out of all installation related-methods up to here:


https://github.com/zed-industries/zed/blob/80bc6c8cc800e23ba79723b0c46b731a62203224/crates/project/src/project.rs#L2916

where the code thinks that the binary installation process had failed,
cleans the existing directory and tries to install the language server
again:

```log

```

The PR extracts away all binary fetching-related code into a single
method that does not fail the entire `get_language_server_command` and
allows it to recover and reuse the existing binary:

This PR updates the `TextSystem` on macOS to allow loading the "Segoe
Fluent Icons" font.

We're using this font in the Storybook to render the `TitleBar` as it
would appear on Windows despite us running it on macOS. This is to make
things easier for iterating on UI design without needing to test on each
individual platform.

However, the "Segoe Fluent Icons" font does not have a glyph for the `m`
character, causing it to run afoul of a precautionary check added in
#4029, which ultimately results in the font not being loaded (and thus
rendering as a missing glyph).

We work around this by simply ignoring this check if the font we're
trying to load is specifically "Segoe Fluent Icons".

I think longer-term we'll need to revisit the behavior in the editor
that is causing the panics when the `m` glyph is missing from the font,
but that's a problem for a different day.

Note that you currently need to install the "Segoe Fluent Icons" font
yourself—either installing it globally or placing the `.ttf` file in the
`assets/fonts` directory—in order to see the icons rendered. I'd like to
look into getting this, but there are restrictions on the distribution
of the font on non-Windows platforms that will need to be followed.

Closes #4926

Release Notes:

- Added support for [JSDoc](https://jsdoc.app) syntax highlighting
([#7224](https://github.com/zed-industries/zed/issues/7224)).

Previously, when `hex_to_hsla` was called with a color string using the
#rgb format, the expansion
did not add alpha values, leading to an incorrect result. This patch
fixes the issue.

In addition to that, parsing has been reworked, and the new function no
longer makes
calls to the global allocator in addition to generation much smaller
code. Parsing should
therefore be a bit more performant.

This PR continues the refinements to the `TitleBar` component.

Here are the notable changes:

- `KeyBindingDisplay` and `PlatformStyle` have been unified into a
single `PlatformStyle`.
- This provides us a consistent way for adapting UI to different
platform styles.
- `PlatformTitlebar` has been renamed to `TitleBar`.
  - The `Platform` prefix was irrelevant.
- The Windows window controls have been factored out into a separate
module and have been componentized.

- Added [object-fit
API](https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit) to the

- Fixes corner radius not working as expected on overflowing elements.

This PR refactors the `CommandPaletteFilter` and
`CommandPaletteInterceptor` to better encapsulate their internals.

Previously these globals and their fields were publicly accessible,
which meant that there was a lot of reaching in and making
modifications.

These changes should make it easier to add additional consumers of these
hooks (right now they're primarily used by Vim mode).

Fixes: https://github.com/zed-industries/zed/issues/9234

This doesn't address `vue` as it has a slightly different install code,
but it should be fairly simple to add - I'll add it in in a follow-up.

This PR will allow all (except `vue`) node-based language servers to
update. It is mostly just throwing in a method into the `NodeRuntime`
trait that is used for checking if a package doesn't exist locally, or
is out of date, by checking the version against what's newest, and
installing. If any parsing of the `package.json` data fails along the
way, it assumes something has gone awry on the users system, logs the
error, and then proceeds with trying to install the package, so that
users don't get stuck on version if their package has some bad data.
Outside of adding this method, it just adds that check in all of the
language server's individual `fetch_server_binary` methods.

Release Notes:

- Added updating for node-based language servers
([#9234](https://github.com/zed-industries/zed/issues/9234)).

Fixes https://github.com/zed-industries/zed/issues/8416

Release Notes:

- Added recent projects into Zed's macOS dock icon context menu ([8416](https://github.com/zed-industries/zed/issues/8416))

This reverts #9053 and #9375 because they introduced a regression on
`main` that broke the titlebars on macOS:


![image](https://github.com/zed-industries/zed/assets/1185253/d046003b-5c66-4a42-9385-623f5d58c9a4)

Two things are off:

- Left padding is missing
- Titlebar height is less than it was before, which means the
traffic-light buttons are not centered vertically

What @as-cii and I noticed while looking into this: the `cfg!(macos)`
macros that were used don't work like that. You need to check for
`cfg!(target = "macos")` etc. Means that on macOS we never used the
macOS-specific code because the condition was always false.

Overall height, we're not sure about.

Fixes https://github.com/zed-industries/zed/issues/9340

The flickering was caused by the pane trying to restore focus on a
`FocusHandle` that wasn't being rendered anymore. This commit uses the
new `WeakFocusHandle` to avoid retaining a reference to focus handles
that don't exist anymore.

Release Notes:

- Fixed a bug that caused flickering when interacting with the language
server logs
([#9340](https://github.com/zed-industries/zed/issues/9340)).

Release Notes:

- Added option to root project folder to collapse all subfolders

In this commit, the Copy trait has been removed from Operator. This
change was necessary due to the value of operator may wish to attach a
motion type, which is not compatible with the Copy trait.

All instances where Operator was previously copied have been updated to
use the clone() or cloned() method instead. This includes function
parameters, variable assignments, and closures.

Successor to #7767.

Release Notes:

- Improved syntax highlighting for TS/TSX and JSON.

Fix #9253

This is the beginning of setting up a flexible way to open items beyond
the text buffer -- think notebooks, images, GeoJSON, etc. The primary
requirement to allow opening an arbitrary file is `try_open` on the
`project::Item` trait. Now we can make new `Item`s for other types with
their own ways to render.

Under the hood, `register_project_item` uses this new opening scheme. It
supports a dynamic array of opener functions, that will handle specific
item types. By default, a `Buffer` should be able to be able to open any
file that another opener did not.

A key detail here is that the order of registration matters. The last
item has primacy. Here's an example:

```rust
workspace::register_project_item::<Editor>(cx);
workspace::register_project_item::<Notebook>(cx);
workspace::register_project_item::<ImageViewer>(cx);
```

When a project item (file) is attempted to be opened, it's first tried
with the `ImageViewer`, followed by the `Notebook`, then the `Editor`.

The tests are set up in a way that should make it _hopefully_ easy to
learn how to write a new opener. First to go after should probably be
image files.

This PR adds a new `rems_from_px` helper function that can be used to
compute rem values based on a pixel value.

This is something we do fairly commonly, where we want to express a size
that is a given pixel size at the base rem size (e.g., "14px when the
rem size is 16px").

`rems_from_px` helps make the intent more explicit, as well as prevent
the base rem size from being duplicated everywhere.

Note: Ideally we would want `rems_from_px` to be `const`, but that
depends on https://github.com/rust-lang/rust/issues/57241.
