feat(brain+ui+app): Triggers — passive Aufweck-Quellen fuer ARIA

ARIA hatte bisher nur ein "User fragt → Brain antwortet"-Modell. Neu:
Trigger laufen passiv im Hintergrund (kein LLM-Call) und wecken ARIA
nur dann auf wenn ein Event tatsaechlich passiert.

Drei Typen, zwei aktuell implementiert:
  timer   — einmalig zu festem ISO-Timestamp ("erinner mich in 10min")
  watcher — Polling alle N Sek einer Condition, feuert bei True mit Throttle
            (z.B. "disk_free_gb < 5", max 1x/h)
  cron    — Platzhalter fuer spaeter

aria-brain/triggers.py
  CRUD auf /data/triggers/<name>.json + /data/triggers/logs/<name>.jsonl.
  create_timer, create_watcher, mark_fired, list_logs, etc.

aria-brain/watcher.py
  Built-in Condition-Variablen: disk_free_gb, disk_free_pct, uptime_sec,
  hour_of_day, day_of_week, rvs_connected, memory_count.
  Sicherer Condition-Parser via ast — Whitelist auf Vergleich + BoolOp +
  Name + Const. Kein eval, kein exec, keine Builtins.

aria-brain/background.py
  Async Loop laeuft alle 30s, sammelt einmalig Variables, geht durch
  Trigger-Liste, _should_fire-Check (Timer: fires_at vergangen / Watcher:
  check_interval + throttle respektiert + condition true). Fire ruft
  agent.chat(prompt, source="trigger") — ARIA bekommt das wie eine
  Push-Nachricht und antwortet via Bridge → RVS → App.

aria-brain/main.py
  /triggers/list, /{name}, /{name}/logs, /timer, /watcher, PATCH, DELETE,
  /triggers/conditions (Variablen + aktuelle Werte). Lifespan-Handler
  startet den Background-Loop beim Container-Start, stoppt beim Shutdown.

aria-brain/agent.py
  Meta-Tools fuer ARIA: trigger_timer, trigger_watcher, trigger_cancel,
  trigger_list. ARIA legt Trigger via Tool-Call selbst an wenn Stefan das
  wuenscht. Side-Channel-Event 'trigger_created' wird in chat-Response
  mitgeschickt damit App + Diagnostic eine Bubble zeigen.

aria-brain/prompts.py
  Neue System-Prompt-Section: Liste aktiver Triggers + verfuegbare
  Condition-Variablen mit aktuellen Werten + Operatoren-Erklaerung.
  ARIA weiss damit immer was es schon gibt und welche Vars sie nutzen kann.

bridge/aria_bridge.py + rvs/server.js
  trigger_created als neuer RVS-Message-Type, Bridge forwarded das aus
  data.events analog zu skill_created.

diagnostic/index.html
  Neuer Top-Tab "Trigger". Liste mit Type-Badges (⏱ TIMER / 👁 WATCHER),
  Status, Fire-Count, last_fired. Aktivieren/Deaktivieren + Löschen pro
  Trigger. "+ Neu"-Modal mit Type-Dropdown, Timer-Minuten oder
  Watcher-Condition + Vars-Anzeige + Throttle. Info-Modal-Eintrag mit
  Erklaerung. Live-Bubble im Chat wenn ARIA selbst einen anlegt.

android/src/screens/ChatScreen.tsx
  trigger_created RVS-Handler → eigene Bubble (gelber Border, "⏰ ARIA
  hat einen Trigger angelegt", Type/Detail/Message/Zeit). ChatMessage
  bekam triggerCreated-Feld. Lokal-only-Schutz beim Server-Sync analog
  zu skill_created.
