Deck: echo what voice awareness hears into the feed

[MyNamesEMurray]

Summary

Every line voice awareness transcribes — your mic, and the party channel if enabled — now appears in the deck feed as a faint 🎙 row, so when a ghost reacts oddly you can see exactly what the transcription thought you said (mishears included).

Changes

• Server: each transcript line broadcasts a new ephemeral heard WS event (channel: mic|party, party carries its configured label). Gated by transcript.showInFeed (default on), read live and registered as a hot path — toggling it in Settings applies without a relaunch.
• Deck: heard rows render faint + italic, deliberately styled as sensor readout rather than chat — mic lines right-aligned like your typed messages, party lines left-aligned with the label ("Discord · 'nice shot dude'"). Tooltip explains what they are (EN + ES). DOM capped at 30 heard rows so hours of talking can't grow the feed unbounded.
• Isolation guarantees (the important design decisions):
  • never enters history — the brain already receives the transcript window separately, so no double-feeding or prompt pollution;
  • never persisted, never in the recap export;
  • never on the on-stream overlay (its client ignores the event type) — mishears stay private to you.
• Settings → Voice checkbox, config.example.json default, README config row + voice-awareness bullet.

No Release-Bump trailer → rides as a patch. Shout if you'd rather this one counted as a minor.

Verification

• E2E on a live server with two real tailed transcript files: mic line arrives as heard{channel:mic}, party line as heard{channel:party, label:"Discord"}; toggling transcript.showInFeed off saves with applied: true (hot, no restart) and suppresses subsequent events while state.lastHeard keeps updating; chat history stays empty throughout.
• Full CI reproduction: syntax (incl. inline HTML scripts), config validation, 45-test suite, smoke — green.

Risk & rollout

• Default-on changes what voice-awareness users see in the deck (that's the point); one checkbox turns it off, live.
• Overlay and prompts provably untouched — no cost impact, no ethics surface.

Checklist

• npm run smoke passes locally (or CI is green)
• Follows the design language in DESIGN.md (if UI changed)
• AI-labeling / "simulated viewers" guarantees intact (if bot output or overlay changed)
• Docs updated (README / config reference) if behavior or config changed
• Targets main
