Release Notes:

- Fix clicking the notes icon when people are in the channel (preview
only)

Release Notes:

- Add user avatars to channel chat messages
- Group messages by sender
- Fix visual bugs in new chat and note buttons

Also, remove logic for implicitly marking chat messages as observed when
they are fetched. I think this is unnecessary, because the client always
explicitly acknowledges messages when they are shown.

Release Notes:

- Fixed a bug where chat messages were shown out of order (preview only)

Release Notes:

- Fixes a panic in vim when incrementing a non-number.

This PR adds a mechanism for notifying the client when a channel note
has been edited or a message has been changed.

TODO: 
- [x] Fix infinite loop when opening the chat panel
- [x] Switch to client-side ack model of observation detection
- [x] Add client-side-only change detection (e.g. for when a channel
note is open locally but not focused)
- [x] Review implementation / query performance.
- [x] Fix lack of ACK on restart for channel buffers
- [x] remove channel note opening on click
- [x] Fix channel messages sent while chat channel is in the background
not showing the channel as changed.

Release Notes:

- N/A

Release Notes:

- Clicking on a channel in the sidebar will now join the channel and
open the notes
- If you join a channel that already shared projects, you will join the
projects automatically and follow the host.
- Clicking on the current channel in the sidebar will re-open the notes.
- Chat can now be accessed from the right click menu of channels.


- (probably not worth mentioning) Various improvements to hover states
and tooltips in the collab ui; and if you click on a channel while in
another call, confirm before switching.

Before this change if you joined a project without clicking on the
notification it would never disappear.

Fix a related bug where if you have more than one monitor, the
notification was only dismissed from one of them.
