This PR updates the `zeta` crate to use the predictive edit DTOs defined
in the `zed_llm_client` crate.

This way we aren't duplicating their definitions (and risk them going
out of sync).

This PR renames some bindings from `data_collection_permission` back to
`can_collect_data`, as the latter name is clearer on account of being a

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.

Release Notes:

- Added the ability to run the `cancel language server work` action

This PR builds on #21258 to make it possible to use HEAD as a diff base.
The buffer store is extended to support holding multiple change sets,
and collab gains support for synchronizing the committed text of files
when any collaborator requires it.

Not implemented in this PR:

- Exposing the diff from HEAD to the user
- Decorating the diff from HEAD with information about which hunks are
staged

`test_random_multibuffer` now fails first at `SEED=13277`, similar to
the previous high-water mark, but with various bugs in the multibuffer
logic now shaken out.

This long standing bug was caused by `Pane`'s focus_in handler bouncing
the focus to another handle.
Because focus resolution happens _after_ a frame has been rendered, the
only way to deal with this case is to schedule another frame to be
redrawn. However, we where suppressing all window refreshes that occur
during a focus transfer, causing this focus change to be completely
missed. However, changing this behavior can lead to infinite notify
loops, due to drawing a frame causing another to be rendered.

This PR fixes this problem narrowly by adding an `on_next_frame()`
callback in the pane's focus handle, so that the focus changes take
effect almost immediately. But only for this case, where we know it
doesn't cause infinite notify loops.

TODO:
- [x] Fix the infinite notify loop bug or determine a third way to fix
this lag

Release Notes:

- Fixed a bug where shifting focus to the terminal panel could be slow

Fixes #22939
Fixes #23970

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.

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

## 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:

- 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.
