feat: serveur MCP, heures calmes, mode mission, widget glanceable, barge-in (v2.4.0) (#14)

Serveur MCP local
- Endpoint /mcp (JSON-RPC 2.0, Streamable HTTP, réponses JSON) sur le serveur
  webhook : initialize, tools/list, tools/call, ping. Même secret que le
  webhook. 14 outils : capture_screen (image MCP), lock_session, open_app,
  open_url, media_key, clipboard_get/set, find_files, speak_text,
  notify_user, set_hud_state, get_app_status, get_conversation_history,
  show_message. Les outils UI transitent par IPC vers le renderer.
- Les mêmes actions système sont proposées au modèle en chat completions.

Notifications
- Heures calmes (plage horaire, franchissement de minuit), mots prioritaires,
  échecs de crons toujours lus, résumé vocal des messages entrants (n premières
  phrases), thème nuit automatique, compteur de non-lus.

Conversation
- Mode mission : bouton dans la barre de commande, second modèle Hermes
  (hermes.missionModel) pour les tâches longues.
- Barge-in : la parole de l'utilisateur coupe la voix ; seuil d'énergie et
  ratio relevés pendant la synthèse pour ignorer l'écho.

Widget compact
- Bandeau glanceable : état, dernière phrase, non-lus, indicateurs heures
  calmes et mission.

Tests : 28 tests unitaires (heures calmes, priorité, résumé), e2e Electron
sous Xvfb : MCP initialize/tools/list/tools/call (presse-papiers, capture en
image, état et message via le renderer), bandeau compact, aucune erreur.
