Detect games with native process exit watchers, own OBS on a background worker, and persist settings and recoverable session timelines. Place segments by split frame counts, recover capture with honest gaps, and finalise on game exit or explicit Quit. Keep the current recording alive after GPUI closes its last window, then exit when the game ends. Add an end-to-end rig covering recording, recovery, exact packet-count offsets, disk library reload and clean Quit.
