Résumé

Trois features M5 dans fractal-ai :

#61 — Résumé de conversation IA

SummarizeRequest : collecte jusqu'à 200 messages, construit le prompt
ConversationSummarizerVm : état UI (Idle → Collecting → Generating → Done)
Prompt configurable en TOML

#66 — Mode Voice-to-Voice

TtsEngine trait async : synthesize(), health_check()
PiperEngine : subprocess piper (modèles locaux ~50 MB)
EspeakEngine : subprocess espeak-ng (fallback léger)
VoiceToVoiceState : machine d'état Idle → Listening → Transcribing → WaitingAgent → Synthesizing → Playing → Ended

#67 — Réponses programmées

ScheduledReply + ScheduleStatus : Pending/Sent/Cancelled/Failed
ScheduledReplyStore : schedule(), cancel(), due_replies(), mark_sent()
Persistance SQLite planifiée (stub in-memory)
11 tests unitaires au total

Closes #61, #66, #67

Plan de test

cargo test -p fractal-ai passe
SummarizeRequest::truncate() garde les 200 messages les plus récents
PiperEngine::health_check() → Unavailable si modèle absent
ScheduledReplyStore::due_replies() retourne les messages dont send_at ≤ now
