While working on Assistant2, I noticed that the `LanguageModelSelector`

Some VPN configurations require that websockets present a user agent.
This adds it in directly for the repl usage. I wish there was a way to
reuse the user agent from the `cx.http_client`, but I'm not seeing a
simple way to do that for the moment since it's not on the `HttpClient`
trait.

No release notes since this feature hasn't been announced/exposed.

- Add and wire through git method stubs

`LanguageModel::stream_completion_text` can poll the `stream_completion`
stream (ultimately a `futures::Unfold`) after it's returned
`Ready(None)`, which leads to a panic; avoid this by fusing the stream.

- Fixed a panic when streaming language model completions

Improve behavior of ctrl-a/ctrl-e home/end in emacs keybind.
Follow up to #21921 to add those to Linux emacs keymap too.

Release Notes:

- emacs: Improved `ctrl-a` / `ctrl-e` / `home` / `end` behavior
- emacs: Added for `ctrl-s` / `ctrl-r` / `ctrl-g` for navigating buffer
search results

When a user types, chances are the model will anticipate what they are
about to do. Previously, we would continuously cancel the pending
completion until the user stopped typing. With this commit, we allow at
most two completions to race with each other (the first and the last
one):

- If the completion that was requested first completes first, we will
show it (assuming we can interpolate it) but avoid canceling the last
one.
- When the completion that was requested last completes, we will cancel
the first one if it's pending.

In both cases, if a completion is already on-screen we have a special
case for when the completions are just insertions and the new completion
is a superset of the existing one. In this case, we will replace the
existing completion with the new one. Otherwise we will keep showing the
old one to avoid thrashing the UI.

This should make latency a lot better. Note that I also reduced the
debounce timeout to 8ms.

Most notably, adding a current iteration of a possible logo to feel it
out! :) Also, I'm hiding the input and instructions container after the
review has been sent. In the future, if we allow changing an already
sent review, we can change this behavior.

The Linux watcher was unconditionally watching the parent directory of
every watched path. This is needed in the case of config files that may
not exist when the watch is set up, but not in other cases. Scoping the
parent watch more narrowly cuts down on the amount of error logging from
irrelevant file change notifications being sent to Zed (in my case it
was picking up changes to a random file in `$HOME`).

Closes #20676

Release Notes:

Adds a simple git placeholder panel for us to iterate from. Also
includes a number of assets from the git prototyping branch that we will
use.

Note: This panel is staff flagged for now.

Workaround for upstream issue where yaml-language-server

Trivial, but makes us not look outdated.

Still TODO:

* [x] Factor out `start_language_server` so we can call it on register
(instead of on detect language)
* [x] Only call register in singleton editors (or when
editing/go-to-definition etc. in a multibuffer?)
* [x] Refcount on register so we can unregister when no buffer remain
* [ ] (maybe) Stop language servers that are no longer needed after some
time

Release Notes:

- Fixed language servers starting when doing project search
- Fixed high CPU usage when ignoring warnings in the diagnostics view

Currently only support 2 color stops with linear-gradient. I think this
is we first introduce the gradient feature in GPUI, and the
linear-gradient is most popular for use. So we can just add this first
and then to add more other supports.

This is behind the Assistant v2 feature flag. As @maxdeviant and I
discussed, the state is currently decoupled from the Assistant Panel's
state, although in the future we plan to introduce a way to refer to
conversations from the panel. Also, we're intentionally duplicating some
code with the v2 panel right now; the plan is to do a future PR to make
them share code more.

Release Notes:

This changes the behavior of how we display inline completions and
non-inline completions (i.e. completion menu).

Previously we would never show inline completions if a completion menu
was visible, meaning that we'd never show Copilot/Supermaven/...
suggestions if the language server had a suggestion.

With this change, we now display the inline completions even if there is
a completion menu visible.

In that case `<tab>` then accepts the inline completion and `<enter>`
accepts the selected entry in the completion menu.

Release Notes:

- Changed how inline completions (Copilot, Supermaven, ...) and normal
completions (from language servers) interact. Zed will now also show
inline completions when the completion menu is visible. The user can
accept the inline completion with `<tab>` and the active entry in the
completion menu with `<enter>`. Previously, `<tab>` would also select
the active entry in the completion menu.

If the instructions are added as the input placeholder, when in a
smaller window size (like the one from the screenshot), scrolling is
needed to see them all. So, thought of extracting it out of there. Also
thought it looked more refined this way!

Related to #21481 ; it fixes a bunch of hotspots I saw while looking at
the provided profiles. MultiBuffer still takes up 100% CPU on the
foreground thread for me - this time around it's on selection updates
(when dragging the selected text towards an edge of a screen).

This PR adds keyboard shortcuts to common interactions you might want to
do in the Zeta rating panel.

This PR also adds a way to fake inline completion requests, as well as
the test data used to create this PR, to make it easier to adjust the UI
in the future.

It also changes the status bar from the text "Zeta" to "ζ", because I
thought it looked cool.

Release Notes:

- Improved LSP resolution of documentation for completions. It now
queries documentation for visible completions and avoids doing too many
redundant queries.

---

In #21286, documentation resolution was made more efficient by only
resolving the current completion. However, this meant that single line
documentation shown inline in the menu was missing until scrolled
to. This also meant that it would wait for navigation to resolve
completion docs, leading to lag for displaying documentation.

This change resolves this by attempting to fetch all the completions
that will be shown. It also mostly avoids re-resolving completions. It
intentionally re-resolves the current selection on navigation, as some
language servers will respond with more information later on.

Closes #21688

This change adds two new methods to the cursor_style_methods function in
the gpui_macros crate (according to the Tailwind CSS documentation
https://tailwindcss.com/docs/cursor):
1. `cursor_nesw_resize`: Sets the cursor style to nesw-resize when
hovering over an element. This is useful for indicating resizing
diagonally from top-right to bottom-left.
2. `cursor_nwse_resize`: Sets the cursor style to nwse-resize when
hovering over an element. This is used for resizing diagonally from
top-left to bottom-right.
