The Tauri bridge connected to the daemon once at startup and held a single
stream with no recovery: when the daemon exited (Restart/Stop, crash, or an
update), the reader emitted spacesh:disconnected and died, and every later
request went through the dead writer forever — the GUI was permanently stuck
(settings frozen, offline). Since the bridge is Rust-side state that survives
a webview reload, even Cmd+R didn't recover it.
- bridge.rs: requests now reconnect-and-retry on failure with a single-flight
guard (generation counter) so concurrent failures collapse into one
reconnect and never open duplicate connections; a 5s reply timeout catches
silently-dropped connections. ensure_daemon respawns the daemon if it
exited. On success the bridge emits spacesh:reconnected.
- App.tsx: on spacesh:reconnected, bump a connection epoch that keys
LayoutEngine, remounting terminals so they re-attach (snapshot + live stream)
to the restarted daemon; also reload health/config/status.
- Settings: drop the Stop button — with lazy daemon spawn any GUI request
resurrects the daemon, so an in-GUI "stop" is contradictory. Restart now
works end to end (shutdown → reconnect respawns → panels re-attach).
