fix(trigger): Trigger-Antworten landen jetzt im Chat — Brain → Bridge Push

Bug: Wenn der Brain-Background-Loop einen Timer/Watcher feuert, ruft
er agent.chat() direkt im eigenen Prozess. Die Antwort wurde nur ins
Trigger-Log geschrieben — kein RVS-Broadcast, kein TTS, nichts in
App/Diagnostic sichtbar.

Fix: Bridge ↔ Brain bekommen einen internen HTTP-Push-Kanal.

Bridge (Port 8090, nicht exposed, nur aria-net intern):
  asyncio.start_server-basierter HTTP-Listener.
  POST /internal/trigger-fired
    body: {reply, trigger_name, type, events}
  → _handle_trigger_fired feuert Side-Channel-Events
    (trigger_created/skill_created/location_tracking) erst,
    dann _process_core_response(reply) — exakt der gleiche Pfad
    wie normale Chat-Antworten (Chat-Bubble + TTS + chat_backup).

Brain background.py:
  Nach agent.chat() in _fire wird agent.pop_events() ausgelesen
  und zusammen mit dem Reply via urllib an aria-bridge:8090
  gepostet (run_in_executor damit es den asyncio-Loop nicht
  blockiert). Failures werden geloggt, der Trigger selbst bleibt
  trotzdem als 'fired' markiert.
