refactor(app): extract focused window lifetime

Browse source 
Move the exact retryable shutdown manifest, typed root snapshot, terminal reporting, and native-window-last release out of GameWindow. Keep session and GPU convergence as hard barriers while reporting persistent physical callback cleanup without stranding dependent owners.

Result: `GameWindowLifetime` owns the typed root snapshot, 18-stage manifest,
transaction progress, terminal report, and native window. Clean, soft-failure,
hard-failure, native-failure, retry, reentrant, and never-run paths are pinned.
The UI host remains explicitly rooted through failed physical detach until the
native edge is gone; successful finalization releases the completed lifetime
graph, while abandonment retains it. No shutdown stage remains in `GameWindow`,
which is now 1,625 raw lines. App Release passes 3,441 tests / 3 skips and the
complete Release suite passes 7,813 / 5 skips.
