Latency plan P0.4/P0.6: the fixed 250 ms advanced-color settle becomes a 25 ms poll of the CCD state (ceiling 250 ms, ring still sized FP16 from the successful enable either way), and wait_for_attach waits on the driver's frame-ready event (20 ms cap for the status-code polls) instead of a blind 20 ms sleep, which also sharpens the P0.1 stage stamps.
