MC2 Final (D16 f): Voice-Metrik-Reste raus + README auf Final-Stand (C15)

f) Lucy/Voice-Reste aus dem MC2-Web-UI entfernt (kein "Sprechen"-Tab mehr):
   VoiceLatencyCard + Sprach-Latenz-Plumbing (queries/api-Typen) und der
   Backend-Leseendpoint /voice/metrics raus. Der Proaktivität-/Alarm-Kanal
   (/voice/announce, /alarm) und die STT/TTS/chat-Proxys bleiben unberührt.
C15) README auf den Final-/Autonomie-Stand aktualisiert (Mem0 statt SQLite-MCP,
   live+eingefroren, Lucy als eigenes Repo, Fangnetz-Updates/Werkstatt).
