This PR adds APIs for voice chat to our live kit integration

Release Notes:

- N/A

When multiple panics occur at the same time (usually because one thread
panics, and another thread joins it), multiple panic JSON objects can
get written to the same panic file. The resulting file won't be valid
JSON.

This PR addresses that problem via two changes:
* Format panic files as single-line JSON objects
* When a panic file  isn't valid JSON, try taking the first line

In the future, we could try combining all of the backtraces, but for
now, I just want to avoid a problem of not reporting a panic at all.

Release Notes:

- Fixed a problem with Zed's internal crash reporting.

This PR updates some dock behaviors. Now the toggle-dock commands
(cmd-j/b/r) also toggle focus. This also adds zoom serialization to the
docks.

Release Notes:
- Bug fix: Toggle dock commands (cmd-j/b/r) now move focus 
- Bug fix: Dock zoom is now restored with the rest of the workspace

This fixes a regression introduced in
https://github.com/zed-industries/zed/pull/2560, where panic reports did
not include backtraces. The problem was that in that PR, I assumed we
could retrieve file paths for symbols in our backtraces. But actually,
that functionality only works when the app is built locally, and a
`.dSYM` file can be magically found by the OS. We don't ship those dSYM
files with Zed, so panic symbols do not have file paths available.

Panic backtraces will still be more useful and less noisy than before
though: we will strip out frames for which we don't have symbol names,
and remove leading panic-handling stack frames from the backtraces.

Release Notes:

- N/A

This PR adds internal docs directly to the codebase.

There are a few goals here:

- Make it easier to document our internal processes
- Put the documentation where people already are
- Allow changes to be in sync with PRs
- Make it easier for people coming in to discover our docs and onboard
faster.

With 2 more people joining us in the next few weeks it would be great to
get these up.

Release Notes:

- N/A (No public facing changes)

This completes the bundle changes that will be needed to access voice,
as well as adds permissions for accessing other MacOS services, the
camera, and the necessary permissions for plugins. This was developed by
combining the entitlements of iTerm and VSCode, cross-referenced with
the entitlements of Firefox. 

Release Notes:

- Fixed a bug in enabling authorization for macOS services (preview
only)

This updates our dependency on cargo-bundle to point at a fork I've
created that adjusts the latest version's behavior to work for our use
case. This PR also updates the Zed Info.plist to include the following
keys:

- NSSystemAdministrationUsageDescription
- NSAppleEventsUsageDescription
- NSBluetoothAlwaysUsageDescription
- NSCalendarsUsageDescription
- NSCameraUsageDescription
- NSContactsUsageDescription
- NSLocationAlwaysUsageDescription
- NSLocationUsageDescription
- NSLocationWhenInUseUsageDescription
- NSMicrophoneUsageDescription
- NSSpeechRecognitionUsageDescription
- NSRemindersUsageDescription

Release Notes:

- Bug fix: Allow applications run via the Zed terminal to request
authorization for macOS services (e.g. microphone and camera)

This pull request is a significant overhaul of the assistant panel,
which now uses a simple `Buffer` as opposed to a `MultiBuffer` to show
messages. Specifically, we track the start of each message with an
anchor located right after the newline (or `Anchor::MIN` for the first
message). When the anchor becomes invalid (that is, the newline is
deleted), we merge the message with the preceding ones. Crucially,
messages don't actually get deleted so that, if the newline anchor
becomes valid again (such as when undoing/redoing), we can restore the
messages as well.

As part of this overhaul, we are also improving the scrolling behavior
to maintain the viewport stable only when editing or moving the cursor,
but otherwise leave the scroll position unchanged when manually
scrolling up or down.

Note that with these changes, we are limiting access to the assistant to
users on preview (and dev), as we want to polish the behavior a little
more before shipping to the general public. Users on stable will still
be able to see the default settings/keybindings of the assistant, but I
think that's okay, as they won't be able to do anything with them.

Release Notes:

- Added support for undo/redo in the assistant (preview-only)
- Improved the scrolling behavior of the assistant when it was
generating responses. Now Zed will keep the viewport stable only when
editing or moving the cursor, but otherwise leave the scroll position
unchanged when manually scrolling up or down (preview-only)
- Changed the icon of the assistant panel (preview-only)

**Note for @JosephTLyons: given that we're feature flagging this, let's
make sure things on stable look reasonable and work correctly. Things to
look out for: ensure a stock installation works, changing the settings
on stable works, changing the keybinding on stable works.**

The worktree has a lot of tests. Let's reduce their indentation, and
make it easier to navigate to them. We deserve it.

Just doing this in its own PR, to minimize conflicts.

Release Notes:

- N/A

Per @JosephTLyons request I've added a language setting for comment
continuations.
