## Context
While looking through the client crate, I noticed that some of the old
functions and variables were still using gpui::model name that was
deprecated during the gpui3 transition. This PR renames those instances
of model to entity to be more inline with gpui3.

In addition, I also renamed `model` to `entity` in cases found by the
below search terms given by @someone13574

- model = cx.
- model: Entity
- model: &Entity
- OpenedModelHandle
- model.update
- model.upgrade
- model = .*\.root (regex)
- parent_model
- model = cx.new
- cx.spawn(move |model

This fixes a "subtract with overflow" error that could happen in debug
mode when viewing the project diagnostics.

From git bisecting, I think that this behavior was introduced by
https://github.com/zed-industries/zed/pull/21942. It seems like it's
possible in some cases for the excerpt-expansion heuristic to cause the
excerpt's `context` range to start *after* the excerpt's `primary`
range. We should probably revisit that heuristic at some point, but it
also seems reasonable to handle that situation at this layer, rather
than overflowing.

Adds a button to the theme selector to help people find more themes in
the extension store.

Release Notes:

- Added a way to access the extension store from the theme selector to
make it easier to find new themes.

It should be 200k (with 100k output). I can't find anything that puts it
at 20k and the changeover in
https://github.com/zed-industries/zed/commit/2f8237492641b4c97f61977a39f8a10225578a6d
only changed the name from o1-mini to o3-mini

Regressions in #24024:

* `+` was no longer included between modifiers and key
* Multi-character keys like "control" were displayed all lowercase,
whereas before they were all uppercase like "CONTROL". Now they are
capitalized, so "Control".
* Brings back icon for tab key.

We now treat new files that have no content as not-dirty. This fixes the
git diff view when deleted files are present.

It also fixes a long-standing bug where `zed RAEDME` and then closing
the tab would prompt for "unsaved changes" when there were none.

Release Notes:

- Fixed a bug where closing an empty, named, file would warn about
unsaved content.

+ add docs and simplify logic around popover order

Release Notes:

Release Notes:

- Fix display, revert and undo of deleted hunks when the file is empty.

We think this could fix issues around view invalidation during focus
handling.

I want to run CI on this and see.

Creates an indents.scm file for bash and adds regexes for
`{increase,decrease}_indent_pattern` in
`crates/languages/src/bash/config.toml`
so that autoindent works as expected in bash

Note that this PR does not attempt to handle all cases where indenting
might be desired in bash. I am aiming to support ~80% of what people
want while avoiding the more gnarly/edge cases like indented blocks in
case statements and indenting for associative arrays.
This is done with the explicit hope that someone (possibly from the
community) more familiar with and passionate about bash can come through
at a later date and handle those cases

Closes #23628

- Add basic support for autoindent functionality in bash/shell files

This PR adds docs for icon themes.

Release Notes:

- Fixed some modifier changed events not being present on Linux X11.
This affected things like the project search palette, where holding ctrl
would not cause the split options to appear.

Certain themes define the `created` and `deleted` status colors, but not
`created_background` and `deleted_background`. Previously, Zed would use
`created` and `deleted` colors, and apply a hard-coded opacity change,
but *not* use `created_background` and `deleted_background`, but that
behavior was inadvertently changed in
https://github.com/zed-industries/zed/pull/22994.

This PR restores the old behavior as a fallback. If a theme defines a
status color, but not the corresponding background color, we'll use a
75% transparent version of the foreground color as a fallback.

Release Notes:

- Fixed an issue in certain themes where diffs would render with the
wrong red and green colors for deletions and insertions.

This PR updates the link to the Scheme extension in the docs, as it was
moved to a separate repo in #24078.

I believe this takes care of the remaining events running through the
old flow that requires transformation at the collab server level. I
think all events are now going through `telemetry::event!()`.

For anyone curious where the new telemetry names are coming from, you
can check the `for_snowflake` function within
`crates/collab/src/api/events.rs`, to see how collab is currently
transforming the events going through the old flow.

Now all users in the collab/ssh session can edit the commit input
collaboratively, observing each others' changes live.

A real `.git/COMMIT_EDITMSG` file is opened, which automatically enables
its syntax highlight, but its original context is never used or saved on
disk — this way we avoid stale commit messages from previous commits
that git places there.

A caveat: previous version put some effort into preserving unfinished
commit messages on repo swtiches, but this version would not do that
— instead, it will be blank on startup, and use whatever
`.git/COMMIT_EDITMSG` contents on repo switch
