Cherry-picked assistant_context_editor: Fix patch block not rendering
due to window reborrow (#24461)

This PR fixes an issue where the Assistant patch block was not being
rendered when using "Suggest Edits".

The issue was that the `BlockContext` already has a borrow of the
`Window`, so we can't use `update_in` to reborrow the window.

The fix is to reuse the existing `&mut Window` reference from the
`BlockContext` so we don't need to `update_in`.

Closes #24169.

Release Notes:

- Assistant: Fixed an issue where the patch block was not being rendered
when using "Suggest Edits".

Cherry-picked gpui: Render SVGs at 2x size when rendered in an `img`
(#24332)

This PR adjusts the rendering of SVGs when used with the `img` element
such that they are rendered at 2x their displayed size.

This results in much crisper icons for icons loaded by icon themes:

<img width="1136" alt="Screenshot 2025-02-05 at 7 39 48 PM"

src="https://github.com/user-attachments/assets/47d1fcee-c54d-4717-8fca-9b9d2bc8da9a"
/>

<img width="1136" alt="Screenshot 2025-02-05 at 7 40 01 PM"

src="https://github.com/user-attachments/assets/3061157c-8c88-41c1-a5dc-83ef9cd341cb"
/>

Release Notes:

- Improved the resolution of icons rendered by icon themes.

Cherry-picked Fix the worktree's repository_for_path (#24279)

Go back to a less optimized implementation for now since the custom

Follow-up to https://github.com/zed-industries/zed/pull/24278

This PR ensures we're checking if there's a license-type file in both US
& UK English spelling, and fixes the error logging again, treating for
when the worktree contains just a single file or multiple.

When you have an edit prediction available, you can now also accept it
with `alt-tab` (or `alt-enter` on Linux) even if you don't have an LSP
completions menu open. This is meant to lower the mental load when going
from one mode to another.

We were looking up line layouts without subtracting start row so we
would get the wrong one when scrolled

This is pretty rare but I found a case where `line_layouts` didn't have
the requested line yet, so we now skip rendering the cursor for that
period and avoid panicking.

Chatted with @as-cii about limitations in the `Window::parent_view_id()`
API (see:
https://github.com/zed-industries/zed/pull/24182/commits/662153dcfdd80804f4041761c09c4a309d79f6d4)
and realized that I shouldn't be using the dispatch tree's data
structures as they are layout dependent. I've introduced a new stack to
`Window`, `rendered_entity_stack`, that tracks exactly which view's
elements are being drawn. As such, I've also been able to remove the
`Option<>` around the previous API.

Release Notes:

- N/A

Note that this does *not* involve any breaking code changes.

cc @0xtimsb - I didn't change any settings or anything here. That can
happen separately!

## 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.

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:

We think this could fix issues around view invalidation during focus
