To prepare the way for the AI assistant, we want to revamp the way docks
and panels work. In this PR, we replace the dock as it currently exists
with 3 independent docks at the left, bottom, and right edge of the
workspace. To replace the "expanded" dock, we will introduce a zoom
feature that works on any pane and some panels. When showing a dock with
an active panel that is zoomed, it will automatically appear zoomed.
This replicates the expanded dock experience. If you unzoom, the panel
will still be visible.

### Panels only

We want to simplify these docks to only allow them to contain *panels*.
By doing this, we don't need to give each dock a tab bar, minimizing
clutter in the workspace. Each panel will remember its size, and the
dock will adjust to that size when the panel is toggled. This will allow
each panel to take up the amount of space that makes sense for its use
case.

There will be 3 kinds of panels:

* Project panel: This currently lives in the left "sidebar", which this
PR renames to the left dock. Users will be able to left click the icon
and switch the project panel to the right dock.
* Terminal panel: This is the primary user of the previous dock. Now all
terminals will live in a terminal panel, which can be docked at the
left, bottom, or right. This dock will contain tabs, but only for
terminals. Terminals will still be able to be dragged into the
workspace, but by default, the first new terminal will live in the
terminal panel which lives in one of the 3 docks.
* Feedback: Instead of opening a pane, let's explore making this a panel
instead.

### Status bar icons

A nice feature of this change is that it simplifies our status bar by
eliminating the dock button. We will only show icons for specific
panels. Panel in the left dock will appear at the left side of the
status bar. Panels in the right dock on the far right, panels in the
bottom will appear on the right, to the immediate left of the buttons
for right panels. Left clicking any panel button will allow it to be
redocked to any valid location for that panel.

### Paving the way for the AI assistant

I'm envisioning the assistant living in the far right panel by default.
So in the stock config, you'll have the project panel on the left,
terminal on the bottom, assistant on the right, and code in the middle.
Let's fucking go!

This PR adds project panel settings for disabling git status.

Release Notes:

- Adds `project_panel: { git_status: bool }` to the settings, for
controlling whether git status information appears.

Drop dependency on tokio introduced by async-openai and do it ourselves.

The approach I'm taking of replacing instead of appending is causing issues. Need to just append.

https://linear.app/zed-industries/issue/Z-1657/diff-markers-in-gutter-do-not-show-up-until-after-first-save

Release Notes:

- Fixes a race condition on buffer initialization that would cause git
diffs to not load.

Redo of https://github.com/zed-industries/zed/pull/2504 

This makes the different git locations individually style-able

Release Notes:

- Improve git contrast (preview only)

Reverts zed-industries/zed#2504, due to accidentally pulling in main

This makes the different git locations individually style-able

Release Notes:

* Improve git contrast (preview only)

This PR fixes a bug in the firing of the UpdatedRepositories event which
caused it to flood collaboration with new messages on every file save.

Release Notes:

* Fixed a bug in repository detection that caused it to fire
over-eagerly (preview only)

Previously, restarting a language server did not clear out the
diagnostics that were published by that server. Those diagnostics would
stick around forever.

Release Notes:

* Fixed a bug where restarting a language server would sometimes leave
buffers with stale diagnostics associated with that server.

Note that this PR cannot be cherrypicked into preview, as it relies on
the new settings infrastructure.

Switches settings from `show_scrollbars: "auto"` to `scrollbar: {show:
"auto", git_diffs: true}`.
