This was broken because the panel was created before being added to a
dock. Invert the control order and add `starts_open()` to the Panel
trait (which lets us simplify how this worked for the ProjectPanel too)

Release Notes:

- Improved Chat visibility when joining a call as a guest

Avoids spurious failures when the CI server is going slow

We set up a new CI server recently, and this caused a build to fail

Was running into an issue building live_kit_server after a fresh clone
due to missing dependencies for build.rs. The use of git submodules
wasn't currently documented.

Reverts zed-industries/zed#4236

This causes an infinite loop when opening the language server logs

It looks like bug reports are being moved from
`zed-industries/community` to `zed-industries/zed`. This PR updates the
`feedback` crate to update the GitHub URL to reflect this change.

It looked to me that `registers` was intended to be a link here...if I'm
wrong, feel free to ignore :-)

Now when hovering on a cursor it'll stay around for 2 seconds

Release Notes:

- Improved hovering over collaborators' cursors.

This PR updates the docs to make it clearer that macOS Sonoma is
supported.

Since our last measurements, startup time in Zed had regressed quite
significantly. This was due to several issues:

- We were loading IBMPlex, which we're not really using in the UI.
- Images were being parsed in the foreground, thus blocking the main
thread
- Language models (for semantic index and assistant) were being loaded
in the foreground, thus blocking the main thread
- Interaction with the keychain was blocking the main thread

In addition to these, with this pull request we will now deserialize the
items for a pane in parallel, as opposed to doing so sequentially.

All combined, when running the zed binary directly this brings startup
time from ~350ms to ~210ms on my machine.

Release Notes:

- Improved startup time.

This fixes https://github.com/zed-industries/community/issues/2442 for
me.

Previously, the tab bar buttons would stay when the chat panel was
opened (and received focus) until something else was drawn (or caused a
render?)

With this change, the tab bar buttons are only shown if the pane was
focus.

I'm not sure about the side-effects of this, but the toolbar still seems
to work fine.

This time around, we address the flicker seen in #3857 by querying the active item (that might've just been added),
as it knows whether it has focus even if the parent Pane does not.

We recently doubled the size of the `ELEMENT_ARENA` after someone ran
into a panic due to the arena running out of space.

This adds some logging so that we can hopefully develop a better
understanding of when the element area's allocation is elevated.

This fixes the performance problem we saw in
https://github.com/zed-industries/community/issues/2405.

In a trace we could see that if a font is missing we'd constantly look
it up and never cache that it's missing.

This changes that and does cache the font-is-missing result.

Drawback is that one would need to restart Zed after installing a
missing font that was configured in settings. That seems acceptable for
now, though.

Release Notes:

- Improved rendering performance when configured fonts are missing on
the system.

This fixes a panic we just saw on nightly. It's the first time we see
this panic, so I think it's pretty safe to assume having twice as much
capacity will fix it.

Release Notes:

- Fixed a crash that could sometimes occur when the window contained
lots of graphical elements.

I want to immediately archive the `keymaps` repo tomorrow. This is the
only change that needs to be brought over.
