Fixes#10935
This is a more robust way to detect "is my surface focused" because that
question usually means "is my surface the last focused surface" if a
_different_ surface is not focused. We already have used this pattern
all over but we should extend it to SwiftUI too.
Fixes#2660
Rather than calculate our window frame size based on various chrome
calculations, we now utilize SwiftUI layouts and view intrinsic content
sizes with `setContentSize` to setup our content size ignoring all our
other widgets.
I'm sure there's some edge cases I'm missing here but this should be a
whole lot more reliable on the whole.
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.

Fixes#7236
Supersedes #7249
This removes all of our `focusedValue`-based tracking of the surface
title and moves it completely to the window controller. The window
controller now sets up event listeners (via Combine) when the focused
surface changes and updates the window title accordingly.
There is some complicated logic here to handle when we lose focus to
something other than a surface. In this case, we want our title to be
the last focused surface so long as it exists.
This is a small cleanup change. This provides the Ghostty.AppState
object to any view that needs it within the TerminalSplit view hierarchy
without needing to explicitly define EnvironmentKeys.
