The status bar diagnostic message font size was updated in
https://github.com/zed-industries/zed/commit/1f65effe57b85d126fcb5689d6d37ec3f768502e
but the LSP status message font size remained the same causing a font
size change when swapping between the two

Release Notes:

- Fixed an inconsistency in status bar font size.

Move result count to the left hand side.

This fixes a bug that could cause the cursor to incorrectly report its
start when using `slice` or `seek_forward`, and then calling `prev`. We
didn't notice this because we were not testing those three methods
together.

I suppose this could explain some of the panics we've observed because
we do use `slice`/`seek_forward` followed by `prev` calls in production.

Move semantic & regex buttons to the right hand side.
Add default tab name for the new project search.

The tree sitter elm parser contains a c symbol which collides with other
linked symbols. This PR downgrades the tree sitter elm parser to a
version which doesn't have this problem.

Release Notes:
- Fixed crash when parsing elm files

In https://github.com/zed-industries/zed/pull/2790 I added an extra drag
event on mouse_up which signaled the end of a drag event, as mouse_up
event themselves wouldn't reliably fire if users moved their mouse too
quickly. This broke the assumptions of the terminal element. This PR
adds filters to all current on_drag handlers which removes this new
event.

Release Notes:

- Fixed a bug causing terminal links to never open (preview only)
- Fixed a bug in terminal link detection causing it to miss files with a
`-` in it

Parallelize Vector Database calls for project semantic search.

Release Notes: (Preview-only)

- Parallelize Vector database calls for project semantic search. Cuts
query time by 2/3rds.
- Removed default keymap for old semantic search modal.

Updated app icon and icon system updates

This PR cascades the split resizing to adjacent splits, if the current
split has already hit the minimum size. This PR also adds support for
detecting the end of a drag event to GPUI, via a bool on the dispatched
drag.

Release Notes:

- Made split resizing more flexible

Move semantic search from navigation modal, to project search option.
This PR is intended to be released in Preview only, and requires an
opt-in semantic_index option to enable. Without this opt-in setting
enable, the user should perceive no differences between previous project
search.

Release Notes: (Preview-only)

- Added Semantic Search as a opt-in feature within Project Search
- Show indexing feedback on indexing process within project search view

Release Notes:

- vim: add a mode indicator

I want to use this on another branch, but it's a sweeping change,
so this prepares the ground for it. This can always be reverted if
it doesn't work out.

This PR adds command palette actions for:

- `sort lines case sensitive`
- `sort lines case insensitive`
- `reverse lines`
- `shuffle lines`

Closes out:

- https://github.com/zed-industries/community/issues/658

and partially closing out:

- https://github.com/zed-industries/community/issues/57 (which is
currently a top-ranked issue)

There are issues with dedupe lines and I didn't try to tackle converting
variable names between different conventions. I'll likely close out 57
with a note to just upvote the remaining individual issues

Release Notes:

- added command palette actions for `sort lines case sensitive`, `sort
lines case insensitive`, `reverse lines`, and`shuffle lines`
