This PR depends on #19547 

This PR adds support for tools from context servers. Context servers are
free to expose tools that Zed can pass to models. When called by the
model, Zed forwards the request to context servers. This allows for some
interesting techniques. Context servers can easily expose tools such as
querying local databases, reading or writing local files, reading
resources over authenticated APIs (e.g. kubernetes, asana, etc).

This is currently experimental. 

Things to discuss
* I want to still add a confirm dialog asking people if a server is
allows to use the tool. Should do this or just use the tool and assume
trustworthyness of context servers?
* Can we add tool use behind a local setting flag?

This PR adds support for selecting toolchains for a given language (e.g.
Rust toolchains or Python virtual environments) with support for SSH
projects provided out of the box. For Python we piggy-back off of
[PET](https://github.com/microsoft/python-environment-tools), a library
maintained by Microsoft.
Closes #16421
Closes #7646

Release Notes:

- Added toolchain selector to the status bar (with initial support for
Python virtual environments)

PR #19653 change the code in this diff, which lead to the remote_server
binary trying to load language grammars, which in turn failed, and
stopped languages from being loaded correctly.

That then lead to language servers not starting up.

This change reintroduces what #19653 removed, so that we don't load the
grammar on the remote_server, by ignoring the grammar name from the
config. The tests still all work.

I went with Cmd-Shift-Y on macOS (Ctrl-Shift-Y on Linux) for "yes accept
this individual hunk" - both are currently unused.

I went with Cmd-Shift-A on macOS (Ctrl-Alt-A on Linux) for "accept all
hunks" - both are unused. (Ctrl-Shift-A on Linux was taken, as is
Ctrl-Alt-Y, so although the pairing of Ctrl-Shift-Y and Ctrl-Alt-A isn't
necessarily obvious, the letters seem intuitive - "yes" and "all" - and
those key combinations don't conflict with anything.)

Release Notes:

- Added keybindings for applying hunks in Proposed Changes

@as-cii @maxdeviant @rtfeldman could somebody update this to display the
actual correct key bindings and ship it. I have them hard coded for now.

This PR updates the `/file` command to emit its `SlashCommandEvent`s in
a way that can actually be streamed.

Previously it was buffering up all of the events and then returning them
all at once.

Note that we still don't yet support streaming in the context editor on
`main`, so there won't be any visible changes just yet.

This changes the download logic to not fetch the latest version, but to
fetch the version matching the current version of Zed.


Release Notes:

- Changed the update logic of the SSH remote server to not fetch the
latest version for a current channel, but to fetch the version matching
the current Zed version. If Zed is updated, the server is updated too.
If the server is newer than the Zed version an error will be displayed.

This fixes a debug-only panic when processing filenames. The underflow
that happens in Preview/Stable shouldn't cause any issues (other than
maybe unmarking an entry in the project panel).

Release Notes:

- Changed the update process of the remote server binary to not attempt
an update if we can detect that the current binary is used by another
process.
- Changed the update process of the remote server binary to mark the
lock file as stale in case the SSH connection of the process that
created the lock file isn't open anymore.

This restores all the init behaviour into main again. This means we
never need to call init_ui (and so we can't call it more than once).

Release Notes:

- (Nightly only) fixes a panic when using the cli to open another file
in a running zed.

This should help a bit more the discoverability of the slash commands.

Exploring using the UI font for it, as it is more common for dropdowns
and popovers throughout the app. Feeling like it makes it lighter and
also shorter in width!
