During `layout`, we now pass a mutable reference to the element's
parent view. This is a recursive process that causes the view to
be removed from `AppContext` and then re-inserted back into it once
the layout is complete.

As such, querying parent views during `layout` does not work as such
views will have been removed from `AppContext` and not yet re-inserted
into it. This caused a bug in `KeystrokeLabel`, which used the `keystrokes_for_action`
method to query its ancestors to determine their type id and keymap context.

Now, any time a view notifies, we will cache its keymap context so that
we don't need to query the parent view during `layout`.

This is achieved by moving `available_actions` into `AsyncAppContext` (where
we know no view/window is on the stack) and `keystrokes_for_action` into `LayoutContext`
where we'll fetch the previous frame's ancestors and notify the current view if those
change after we perform a layout.

Add copilot.disabled_globs setting

Focus is now one of the last things that happens during `flush_effects`,
and we shouldn't have relied on `defer` in the first place to verify
focus changes.

Fix "IncomingCallNotification was dropped" error when accepting a call

This was caused by accepting the call, which caused the notification to
be removed. When `active_call.accept_incoming()` finally completed, we
would try to get the app state from it in order to join the project, but
couldn't becuase the view would have already been dropped.

This commit fixes the bug by capturing a weak handle to the app state
when accepting the call as opposed to trying to read it from the view
when the accept completes.

Move methods querying window state into `AsyncAppContext`

Use json_post() request for update requests

Add download and upload metadata to update request

Closes https://github.com/zed-industries/community/issues/1095
by forcing the non-Cancel button to get a focus.
Due to the way macOs handles buttons on modals, the focus gain had to be
achieved via certain button addition order, rather than conventional
"setFocus"-ish API, see the related comment for details.

Fix broken styling in contact finder

This regressed as part of #2372, where we forgot to theme the contact
finder picker differently from the rest of the app.

Fix panic when showing contacts popover via keybinding

Move `debug_elements` to `AsyncAppContext`

Previously, `debug_elements` was available on `WindowContext`. If that
method was called while having a borrow out to a view, it would panic because
the view would already have been borrowed.

By moving it to an `AsyncAppContext` we ensure the method can't be called while
a view is being used.
