Relaunch Bridge after the tray panel dies on hibernate - #23
Conversation
Glow/winit often end the event loop when Windows restores the GPU, and Bridge treated that as a clean exit. Spawn a replacement unless the user quit or an in-app update is already relaunching. Co-authored-by: Cursor <cursoragent@cursor.com>

Disable relaunch at the updater handoff.
download_and_stage() starts the update helper before install_update() sends UpdateEvent::Restarting. If the GUI stops before TrayApp::logic consumes that event, keep_running remains true. The shutdown path can then spawn the old executable after stopping the server. The helper waits only for the original process, so the old executable can start before the helper replaces the binary and launches the update.
Clear keep_running when the update helper starts, while preserving relaunch for failed updates and user exits.
