Previously, the permission request response would not move the state so
it'd stay in the titlebar.

If an update is available, you can now trigger the full download,
install, and restart from a single command palette action. This allows
for a fully keyboard-driven update process.

While an update is being installed, an option to cancel or skip the
current update is also shown as an option, so that can also be
keyboard-driven.

This currently can't be bound to a keyboard action, but that may be
added in the future if there's demand for it.

**AI Disclosure:** Amp was used considerably. I reviewed all the code
and understand it.

This was causing the "no update found" message to never really appear in
the real world.

If there are no windows, we use the standard sparkle driver to drive
the standard window-based update UI.
