This PR makes it so previous messages in the thread are included when
constructing the completion request, instead of only sending up the most
recent user message.

Release Notes:

- N/A

This PR removes an unnecessary `Pane` that was copied over from
`assistant::AssistantPanel` to `assistant2::AssistantPanel`.

Release Notes:

This PR makes it so that the completion text streams into the message
list rather than being buffered until the end.

Release Notes:

- N/A

This is a pure refactor, motivated by wanting to introduce to the
BufferStore new logic for opening staged and committed changes.

I found the `BufferStoreImpl` trait a little bit confusing, particularly
how the different implementors of the trait held a handle back to the
owning buffer store. I was able to reduce the amount of code
considerably (-78 lines) by using a two-variant enum instead, similar to
what we do for `LspStore`, `WorktreeStore` and `Worktree`.

Release Notes:

- N/A

This PR adds in rudimentary functionality for sending messages to the
LLM in `assistant2`.

@bennetbo @as-cii @mrnugget I'm really not liking the hints about AI on
every line. It feels too distracting to me and damaging to the user
experience. I'm wondering if we can hide them and work with design for
other ideas. Or at least talk it through.

Closes #ISSUE

Release Notes:

- pylsp will now use version installed in user venv, if one is
available.

Release Notes:

- Add `string.doc` python syntax highlighting to class and module-level
docstrings.

Previously, only docstrings inside python functions were labeled as
`string.doc`, but docstrings can exist at the class or module level too.
This adds the more specific string type for each of those.

- Unify welcome page event type string structure
- Differentiate between metric telemetry event and diagnostic telemetry
event

Release Notes:

- N/A

This needs scrutinized. Detailed breakdown of what events I kept and
threw out here:

https://zed.dev/channel/app-events-17178/notes

I also removed a few fake events and tossed out json properties that
were being inserted for things we don't have logic to track. See PR
review comments below.

I think the only bad data we have are that we were identifying all node,
pnpm, and yarn projects as 'node' in the `project_type` property, so a
few days of lost data there.

This PR factors the language model selector out into its own
`language_model_selector` crate so that it can be reused in
`assistant2`.

Also renamed it from `ModelSelector` to `LanguageModelSelector` to be a
bit more specific.

Release Notes:

- N/A

This PR breaks ground on a new `assistant2` crate.

In order to see this new version of the assistant, both of the following
must be true:
1. The `assistant2` feature flag is enabled for your user
   - It is **not** currently enabled for all staff.
2. You are running a development build of Zed

The intent here is to enable the folks working on `assistant2` to
incrementally land work onto `main` without breaking use of the current
Assistant for anyone.

This PR overhauls extension registration in order to make it more
modular.

The `extension` crate now contains an `ExtensionHostProxy` that can be
used to register various proxies that the extension host can use to
interact with the rest of the system.

There are now a number of different proxy traits representing the
various pieces of functionality that can be provided by an extension.
The respective crates that provide this functionality can implement
their corresponding proxy trait in order to register a proxy that the
extension host will use to register the bits of functionality provided
by the extension.

Release Notes:

- N/A

* Fixes registration of event handler for xinput-2 device changes,
revealed by this improvement.

* Pushes `.unwrap()` panic-ing outwards to callers.

* Includes a description of what the X11 call was doing when a failure
was encountered.

* Fixes a variety of places where the X11 reply wasn't being inspected
for failures.

* Destroys windows on failure during setup. New structure makes it
possible for the caller of `open_window` to carry on despite failures,
and so partially initialized window should be removed (though all calls
I looked at also panic currently).

Considered pushing this through `linux/x11/client.rs` too but figured
it'd be nice to minimize merge conflicts with #20853.

This PR adds a function, WindowContext::drop_image, to manually remove a
RenderImage from the sprite atlas. In addition, PlatformAtlas::remove
was added to support this behavior. Previously, there was no way to
request a RenderImage to be removed from the sprite atlas, and since
they are not removed automatically the sprite would remain in video
memory once added until the window was closed. This PR allows a
developer to request the image be dropped from memory manually, however
it does not add automatic removal.

Closes #17161

Release Notes:

- Added symlink resolution when opening projects from within Zed.
Previously this only happened within zed's cli, but that broke file
watching on Linux when opening a symlinked directory.

This PR updates the `ExtensionRegistrationHooks` trait to not name the
`ExtensionLspAdapter` type.

This helps decouple the two.

I've observed that Zed's implementation of [Code Actions On
Format](https://zed.dev/docs/configuring-zed#code-actions-on-format)
uses the
[CodeActionContext.only](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#codeActionContext)
parameter to request specific code action kinds from the server. The
issue is that it does not filter out code actions from the response,
believing that the server will do it.

The [LSP
specification](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#codeActionContext)
says that the client is responsible for filtering out unwanted code
actions:

```js
/**
* Requested kind of actions to return.
*
* Actions not of this kind are filtered out by the client before being
* shown. So servers can omit computing them.
*/
only?: CodeActionKind[];
```

This PR will filter out unwanted code action on the client side.

I have initially encountered this issue because the [ZLS language
server](https://github.com/zigtools/zls) (until
https://github.com/zigtools/zls/pull/2087) does not filter code action
based on `CodeActionContext.only` so Zed runs all received code actions
even if they are explicitly disabled in the `code_actions_on_format`
setting.

Release Notes:

- Fix the `code_actions_on_format` setting when used with a language
server like ZLS
