by reworking the inlay hover model:
* avoid storing "hardcoded" coordinates of hovered inlay labels (such as
`InlayOffset`), instead, remember `inlay_id` and apply required
highlights there when hint with the same id is handled
* add randomized tests on inlay highlights
* sped up inlay hint cache lookup by inlay_id

As a downside, background highlights are no long appearing on inlay
hints, but Zed does not receive any tooltips for inlays anyway (r-a does
not send them for some reason, other LSP seem to have no such feature?),
so it does not matter now.
Nontheless, if the logic for displaying hint pop-ups is present and
works for harcoded tooltips in r-a, only background highlight is missing
now.

Release Notes:

- Fixed inlay hint highlights causing panic for certain cases with
"large" characters

Release Notes:

- Fixed a bug that was preventing errors from being shown in the inline
assistant when it was still deployed. (preview-only)

Small fix to update code for rate limiting status.

Release Notes (Preview only)
- Fixed update to only stop updating status, when the rate limit is
reset to None

This allows users to add a keybind to ToggleReplace from Editor/Pane
contexts.

Release Notes:
- Fixed replace in buffer not reacting to keyboard shortcuts outside of
search bar<preview-only>.

Release Notes:

- N/A

This pull request extracts a separate `Codegen` struct that models the
interaction with OpenAI and takes care of diffing, auto-indenting and
reporting regions to highlight.

As part of this refactoring, we're now relying less on the AI model to
indent code. The new logic lets tree-sitter decide how the first line
should be indented. Then, for every subsequent line reported by ChatGPT,
it calculates an indent delta relative to the first reported line and
applies it to the indent level chosen by tree-sitter.

Release Notes:

- Improved auto-indentation when using the inline assistant.

Release Notes:

- vim: Fix counts with operators (`2yy`, `d3d`, etc.)
([#1496](https://github.com/zed-industries/community/issues/1496))
([#970](https://github.com/zed-industries/community/issues/970)).
- vim: Add support for counts with insert actions (`2i`, `2o`, `2a`,
etc.)
- vim: add `_` and `g_`

This PR addresses feedback from @maxbrunsfeld on new replace in buffer.
It fixes:
- missing padding surrounding replace input.
- missing padding around replace buttons.
- missing `.notify` call which made the replace fields not show up
immediately sometimes.

Release Notes:
- N/A

Release Notes:
- Fixed a case where language server download statuses could be skipped.
- Fixed a case where language server diagnostic progress could get stuck
when restarting a language server.

This is still WIP, mostly pending styling. I added a pretty rudimentary
text field and no buttons whatsoever other than that. I am targeting a
Preview of 09.13, as I am gonna be on PTO for the next week.

I dislike the current implementation slightly because of `regex`'s crate
syntax and lack of support of backreferences. What strikes me as odd wrt
to syntax is that it will just replace a capture name with empty string
if that capture is missing from the regex. While this is perfectly fine
behaviour for conditionally-matched capture groups (e.g. `(foo)?`), I
think it should still error out if there's no group with a given name
(conditional or not).
Release Notes:

- Added "Replace" functionality to buffer search.

(and refactor tests to be more linear)

This re-uses the existing repeat infrastructure.

Fixes 2yy, d3d, etc.

[[PR Description]]

Started building out some early components in the storybook using a
modified version of the classic Atomic Design model @mikayla-maki and I
are exploring.

This PR adds a few things:

- `tab`, `tab_bar` and `icon_button` components
- Dynamic documentation for the proc macro generated methods like `w_8`,
`px_2`, etc.
- Continues to build out the Zed workspace demo

Release Notes:

- N/A

This adds primitive interaction with the IME system for keyboard
shortcuts in zed.

- Consult the IME functionality when handling keyboard shortcuts. This
allows you to bind to characters (like " on a Brazillian keybaord, or $
on a Czech keyboard) that aren't typed with an unmodified key.

Release Notes:
- Improved command palette's command ordering; commands are sorted
lexicographically and by command's use count in the current session.

This PR splits `crates/gpui/playground` with two new crates: `gpui2` and
`storybook`.

GPUI 2 re-exports most of `gpui`, but makes some adjustments. I want to
keep the scope focused. This isn't literally version 2.0 of GPUI or
anything. It's just a convenient way to make a create with fewer
dependencies where we can iterate quickly on aspects of GPUI's design.
Most of the focus is on improving our approach to element layout and
styling.

The `storybook` crate is pretty empty for now, but it's where I intend
to start rebuilding interfaces. I welcome anyone else to join me in
this, though until I get one interface fully built, buyer beware. You
may need to pair on it with me.

Unfortunately, their language server implementation uses [VSCode
directly](https://github.com/neovim/nvim-lspconfig/issues/2592), so I
don't think we can bundle it in yet. For reference, I also started
prepping a [Zed
repository](https://github.com/zed-industries/nushell-lsp) for serving
the nu language server but have archived it since discovering the issue.

Release Notes:

- Added syntax highlighting for Nushell script files
