A transcription that landed while the private Whisper service was
restarting (an image roll) crashed hermes_stt_client.py with a raw
urllib ConnectionRefused traceback that got dumped into the
conversation. The client now retries the request with backoff (up to 5
attempts, ~10s - long enough to ride an STT pod restart) and, on a
persistent outage, exits with one concise line ('speech transcription
unavailable...') instead of a stack trace. Delivered via the coordinator
ConfigMap; the next reconcile picks it up.

Port the original #27 detected-language pipeline onto the verified PR #39 prerequisite while preserving the current-main conversation instrument and host continuity changes.
Keep voice selection server-side with no user selector or client voice field. Reuse 207c16ab only for its stricter exact-code trust boundary, omitting malformed or absent language so Piper defaults to Amy.
