This PR is a bit of a last minute change, but I realized there was
actually a third player in the Elixir LSP space who wants support as
well,
[lexical](https://github.com/zed-industries/community/issues/1567). I
realized that the settings arrangement I shipped in this preview
precludes adding a third kind of LSP. I don't have the time to learn how
to fully support this LSP, but I thought I'd at least refactor how the
settings are represented before this hits stable.

Release Notes:

- Changed the new `"elixir": { "next": "on" }` setting to `"elixir": {
"lsp": "next_ls" }`. The `elixir.lsp` setting requires a full restart to
take effect. (Preview only)

fixes https://github.com/zed-industries/community/issues/2098

Release Notes:

- Fixed a bug in Zed's LSP implementation when using Next LS.

Release Notes:

- Added the ability to exclude warnings from project diagnostics. By
default, they will be on but they can be disabled temporarily by
clicking on the warnings icon. The default behavior can be changed by
changing the new `diagnostics.include_warnings` setting.

Release Notes:

- Enabled the `semantic_index` setting by default.

- don't prompt to save a set of unchanged files when closing
(preview-only)

Release Notes:

- N/A

Release Notes:

- Reordered items in project and buffer search bar

Augment current search strategy in semantic search, reducing search
times by ~60%

Release Notes:

- Implemented minimum batch sizes for concurrent database reads.
- Batch embedding matrix multiplication.
- Calculate matmul with ndarray

- vim: Fix ctrl-d/ctrl-u to match vim (when :set scrolloff=3)

remove small dbg! statement in main

Transition generate prompt for inline assist to leverage outline as
opposed to full file.
This enables, us to leverage the inline assist for large files.

Release Notes:

- Change inline assist to use tree-sitter based outlines for code
generation instead of full files

Fixes zed-industries/community#2081

Release Notes:
- Fixed "toggle comment" action not working in CSS buffers.

They should work by exactly half a screen, and also move the cursor.

- Add cmd-k shift-{left,right,up,down} to swap panes in that direction
- vim: Add ctrl-w shift-{h,j,k,l} to swap panes in that direction
([#278](https://github.com/zed-industries/community/issues/278))

Add keybindings for vim (and non-vim)

This PR adds a `Sized` bound to the `StyleHelpers` trait.

All of the individual methods on this trait already had a `Self: Sized`
bound, so moving it up to the trait level will make it so we don't have
to repeat ourselves so much.

There's an open question of whether we can hoist the `Sized` bound to
`Styleable`, but it's possible there are cases where we'd want to have a
`Styleable` trait object.

There were times when events with bad data were being emitted. What we
found was that places where certain collaboration-related code could
fail, like sending an invite, would still send events; those events
would be in a bad state, as certain elements, such as a room, weren't
constructed as expected, causing the event to have missing data. The new
API guarantees that we have data in the correct configuration. In the
future, we will add events for certain types of failures within Zed, to
cover things like invites failing.

This PR removes a leftover `dbg!` from `styleable_helpers!`.

We already removed this in the `gpui2-ui` branch, but getting this on
`main` since @KCaverly pointed it out.

Adding a few bindings to bring first class feeling multiselect to zed's
vim emulation.

gn and gN are similar to similar vim bindings, ga is similar to gA (and
I doubt we need vim's real ga), g> and g< are just made up.

Release Notes:

- vim: `g n` / `g N` to select next/previous
- vim: `g >` / `g <` to skip current selection and select next/previous
- vim: `g a` to select all

- g n / g N to select next/previous
- g > / g < to select next/previous replacing current
- g a to select all matches

This fixes several bugs with how spaces and keyboard commands interact
with channel creating / renaming.

Release Notes:

- Allow cmd-+ in addition to cmd-= for zoom in
([#1021](https://github.com/zed-industries/community/issues/1021)).

Although I had initially thought this was something more to do with
option key handling, it turns out to be a straightforward and reasonable
feature request.
