This PR updates the `gpui::prelude` to not export the `Context` trait
named.

This prevents some naming clashes in downstream consumers.

This PR adds the ability to remove individual pieces of context from the
message editor:

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:

Starting to fine-tune it.

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.

Release Notes:

- Fixes diagnostics not updating in some circumstances

This PR fixes an issue where dev extensions were not working when
uploaded to the remote server.

The `extension.toml` for dev extensions may not contain all of the
information (such as the list of languages), as this is something that
we derive from the filesystem at packaging time. This meant that
uploading a dev extension that contained languages could have them
absent from the uploaded `extension.toml`.

For dev extensions we now upload a serialized version of the in-memory
extension manifest, which should have all of the information present.

Release Notes:

- SSH Remoting: Fixed an issue where some dev extensions would not work
after being uploaded to the remote server.

For debugging #21020. Copy-modified [from async_task
here](https://github.com/smol-rs/async-task/blob/ca9dbe1db9c422fd765847fa91306e30a6bb58a9/src/runnable.rs#L432)

Release Notes:

- Added `show_completions_on_input` and `show_completion_documentation`
per-language settings. These settings were available before, but were
not configurable per-language.

Some of our users ran into a peculiar bug: autoimports with vtsls were
leaving behind an extra curly brace. I think we were slightly incorrect
in always requesting a follow-up completion without regard for last
result of completion request (whether it was incomplete or not).
Specifically, we're falling into this branch in current form:
https://github.com/yioneko/vtsls/blob/037c2b615bf4cfe9dd65d9affc7a155fbb2ca255/packages/service/src/service/completion.ts#L121
which then leads to incorrect edits being returned from vtsls.

Release Notes:

- Fixed an edge case with appliance of autocompletions in VTSLS that
could result in incorrect edits being applied.

The goal of #7115 appears to be to limit the disruptiveness of
completion documentation load causing the completion selector to move
around. The approach was to debounce load of documentation via a setting
`completion_documentation_secondary_query_debounce`. This particularly
had a nonideal interaction with #21286, where now this debounce interval
was used between the documentation fetches of every individual
completion item.

I think a better solution is to continue making space for documentation
to be shown as soon as any documentation is shown. #21704 implemented
part of this, but it did not persist across followup completions.

Release Notes:

- Fixed completion list moving around on load of documentation. The
previous approach to mitigating this was to rate-limit the fetch of
docs, configured by a
`completion_documentation_secondary_query_debounce` setting, which is
now deprecated.
