This fixes a bug where it was possible to put the channel tree into a
bad state by accidentally dragging a channel into itself or one of its
descendants.

This PR extends `Button` with support for an optional icon to be
displayed next to the label.

As part of this, the functionality for displaying an icon within a
button has been factored out into an internal `ButtonIcon` component.
`ButtonIcon` is now used by both `IconButton` and `Button` to
encapsulate the concerns of an icon that is rendered within a button.

Release Notes:

- N/A

This PR adds a new `selected_label` method to `Button`.

This can be used to set a different label that should be rendered when
the `Button` is selected.

Release Notes:

- N/A

This PR adds a new `selected_icon` method to `IconButton`.

This can be used to set a different icon that should be rendered when
the `IconButton` is selected.

Release Notes:

See title

Release Notes:

- N/A

- Adds a placeholder `ButtonStyle::Tinted`.
  - Note: Using this now will just give you a block of `gpui::red()`
- Documents ButtonLike and ButtonStyle to hopefully help make choosing a
button style easier.

We observed some weird behavior in `ContextMenu`, specifically:

- It seems like we don't intercept actions that have been dispatched,
which causes the context menu to stay open.
- The key bindings for editor actions in the context menu seem to come
from Vim

Release Notes:

- N/A

The only missing piece is the context menu, which I'll work on next.

This bug was my fault, something I changed months ago to be more
consistent with VS Code - really strange that it took months for someone
to find out spaces couldn't be used in the project panel.

~I didn't apply this fix to zed2 because I dont think the facilities are
in place to do so (@maxbrunsfeld, @mikayla-maki, is there a system in
place for this that I missed?). I did leave a TODO.~

Fix is now in zed 2.

Release Notes:

- Fixed a bug where spaces could not be inserted when editing file names
in the project panel
([#2308](https://github.com/zed-industries/community/issues/2308)).

This PR makes `Button`s respect the `label_color` that is specified,
provided they are not disabled or selected.

Release Notes:

- N/A

Passes the compiler so it must work!

(though it doesn't show up until we fix pane focus)

Release Notes:

- N/A

This makes things more in-line with `popover_menu`.

* Pane history navigation
* Autosave on focus change
* Setting the window title based on the active path

This PR is a quick-and-dirty approach to clarify what is happening when
a user doesn't have an API key so the assistant opens with the key
editor.

- Adds some text explaining how to close the panel
- Explains that other subscriptions don't cover the assistant, it needs
an api key.
- Helps people understand where to go to get an API key.

This is a Zed 1 change only, a bandaid. Zed 2 will have a better
solution: [Working
issue](https://github.com/zed-industries/zed/issues/3461)

Release Notes:

- N/A

This PR reworks the `ListHeader` component to be more open.

The `meta` method can now be used to append meta items of any element to
the `ListHeader`, and they will be rendered with the appropriate spacing
between them.

Release Notes:

- N/A

Bumps Tree-sitter for
https://github.com/tree-sitter/tree-sitter/pull/2802

Release Notes:

- Fixed a crash that occurred when editing certain Markdown files.
