There is a sparkle-related 'issue' with the previous implementation. When you download/install in the `updateAvailable` state, if you don't install it, then check the updates again. Sparkle loses its downloaded stage in the delegate (it's normal when I use the sparkle source code). This time, when you click install in the `updateAvailable` state, it just uses the previous downloaded package and starts to install, without calling `showReady(toInstallAndRelaunch:)`.
I think removing `readyToInstall` in our customed ui, will reduce one step to install an update for most of the users out there, which makes sense, since the current package is pretty small, only takes a few seconds to download for a normal network, and they intended to install this update.
This mainly allows users who have a pending update but didn't install it
for some time to re-check to see if there is something newer in the mean
time.
This includes multiple changes to clean up the "installing" state:
- Ghostty will not confirm quit, since the user has already confirmed
they want to restart to install the update.
- If termination fails for any reason, the popover has a button to retry
restarting.
- The copy and badge symbol have been updated to better match the
reality of the "installing" state.

understood.
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.

Ghostty now has a release channel build configuration. Current valid
values are "tip" and "stable" but I imagine more will be added in the
future.
The release channel is inferred whether the version we specify with the
`-Dversion-string` build flag has a prerelease tag or not. If it does,
the release channel is "tip". If it doesn't, the release channel is
"stable".
This also adds a configuration to specify the release channel for
auto-updates for the macOS application.
