fix: stale socket detection prevents daemon spawn after crash

isDaemonRunning() only checked file existence of the Unix socket.
A dead daemon leaves a stale socket, causing ensureDaemon() to skip
spawning and client.start() to fail with 'Chrome not connected'.

Replace with a liveness probe: connect, register, verify ack, then
disconnect. On failure, clean up the stale socket.

Also makes bridge handleRequest async to poll for Chrome connection
for up to 15s before rejecting.
