Default final beam 5 -> 2: the accuracy/speed knee - most of beam search's benefit at ~2x greedy instead of ~5x, protecting commit latency on the Jetson (still env-overridable via HERMES_STT_FINAL_BEAM_SIZE). Prompt now also primes common names (Amy, Claude, Hermes) so 'Amy' stops transcribing as 'aiming'.
