becoming too large or too small. (preview-only)

This also removes navigation controls from the terminal panel, given
that terminals don't make use of that feature anyway. When the toolbar
is empty, we'll avoid showing it altogether.

Release Notes:

- Fixed a regression that was preventing the terminal panel from being
searched.

Add release note lines here:

- Fixed a bug that could cause panes to be erroneously zoomed when
toggling modals. (preview-only)

This adds basic ability to interact with OpenAI inside a buffer.

Release Notes:

* If`OPENAI_API_KEY` is defined in your environment, you can now run the
`ai: assist` command to pass the text of your current buffer to GPT-4.
If you're editing a file with a `.zmd` extension, you can also invoke
the model with `cmd-enter.` (preview-only)

This makes the `Toggle{Left,Right,Bottom}Dock` actions deserializable
from empty JSON, so that they can be constructed for the command
palette. It also fixes a bug in GPUI's `available_actions` method, in
which we'd include key bindings for actions of the same type but
different values.

Note that, for now, the command palette will perform the *focusing*
version of the actions. I'm not totally sure this is the right behavior,
but it seems more useful to me.

In this pull request we improved key bindings (as described below) and
added tooltips.

Add these release notes to the panels release notes:

- The left, right and bottom dock can be toggled and focused at the same
time respectively via `cmd-b`, `cmd-r` and `cmd-j`. Holding `shift` will
toggle them without changing the focus.

Fixes
https://linear.app/zed-industries/issue/Z-987/option-enter-doesnt-open-buffer-from-multibuffer-if-on-the-last-line

This was caused by seeking with a right bias, which in the case of the
last excerpt in the buffer would seek past the end of the buffer. This
commit changes the behavior to move the cursor back to the previous
excerpt if we overshoot, to ensure we always land on an excerpt.

Release Notes:

- Fixed a bug that prevented opening excerpts when the cursor was at the
end of a multi-buffer.

https://linear.app/zed-industries/issue/Z-1789/empty-panes-should-not-be-zoomable

The actions in Zed now call this the Terminal Panel and the crate is
called that as well, so I think the tooltip should be updated to use
that same name.

https://linear.app/zed-industries/issue/Z-1188/allow-docks-to-be-visible-on-left-bottom-right

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.
