feat(B-TRIG): Trigger-Kern konsolidiert — generischer Dispatcher, UI-Event-Typ, 4 Trigger-Typen

B-TRIG-GEN: app/core/trigger_dispatcher.py (NEU) — generischer Event→Automation Dispatcher
- Wildcard EventBus Subscribe → matcht AutomationDefinition mit trigger_type=event
- Keine hardcodierte Event-Liste mehr — alle Outbox Events können Automations triggern
- Registriert in main.py lifespan + worker.py on_startup

B-TRIG-UI: UI-Event Trigger-Typ
- trigger_type Pattern um „ui" erweitert (event/schedule/manual/ui)
- UI-Events laufen ephemeral über EventBus → TriggerDispatcher → run_automation
- UI-Events NIEMALS in Outbox (is_ui_event() Guard)

B-TRIG-CRON: Cron/Heartbeat verifiziert — bestehender Pfad funktioniert
B-TRIG-MAN: Manual-Trigger verifiziert — bestehender Pfad funktioniert

B-TRIG-TEST: 10 Tests in test_trigger_core.py — alle grün
- Domain Event, UI Event (ephemeral), Cron, Manual, alle nutzen selben Execution-Kern
B-TRIG-DOC: Plugin-Dev-Guide Kapitel 10 mit Implementierungsdetails erweitert

+"""Trigger dispatcher — routes events to matching automation definitions.
+
+This module provides the **generic** bridge between the EventBus and the
+automation execution engine.  It replaces the previous hard-coded event
+handler stubs (``on_contact_created`` etc.) with a single wildcard
+subscriber that queries the database for matching
+``AutomationDefinition`` rows and dispatches them through the common
+``run_automation`` execution core.
+
+Two event categories are supported:
+
+1. **Domain events** (durable, via Outbox → Worker → EventBus)
+   - trigger_type = ``"event"``
+   - trigger_config = ``{"event_name": "contact.created"}``
+   - Any event published to the EventBus (either directly or via the
+     outbox processor) can trigger an automation.
+
+2. **UI events** (ephemeral, via WebSocket → EventBus only)
+   - trigger_type = ``"ui"``
+   - trigger_config = ``{"event_name": "ui.contact_selected"}``
+   - UI events are **never** written to the outbox.  They flow directly
+     from the frontend WebSocket handler through the EventBus to this
+     dispatcher.
+
+All four trigger types (event, ui, schedule, manual) converge on the
+same ``run_automation`` execution engine, ensuring consistent condition
+evaluation, action execution, and run logging.

 ## 10. Trigger

+Plugins können durch vier Trigger-Typen aktiviert werden: **Domain-Events**, **UI-Events**, **Cron-Jobs** und **manuelle Trigger**. Alle vier Typen konvergieren im selben Execution-Kern (`run_automation`). Webhook-Trigger folgt in Phase G.
+
+### 10.0 Trigger-Typen-Übersicht
+
+| Trigger-Typ | `trigger_type` | Event-Quelle | Durability | Dispatch-Pfad |
+|-------------|----------------|-------------|------------|---------------|
+| Domain-Event | `event` | Outbox → Worker → EventBus | **durable** (at-least-once) | EventBus `*` → TriggerDispatcher → `run_automation` |
+| UI-Event | `ui` | WebSocket → EventBus (ephemeral) | **ephemeral** (keine Persistenz) | EventBus `*` → TriggerDispatcher → `run_automation` |
+| Cron/Schedule | `schedule` | ARQ Cron → `scheduler_tick` | **durable** (ARQ-Queue) | `scheduler_tick` → `enqueue_job("run_automation")` |
+| Manual | `manual` | API-Route `/execute` | **durable** (HTTP-Request) | Route → `run_automation(trigger_type="manual")` |
+
+**Wichtig:** UI-Events (`ui.*`) dürfen **niemals** in die Outbox geschrieben werden. Sie sind ephemeral und fließen direkt über den EventBus.
 
 ### 10.1 Domain-Event-Trigger (durable)
 
-Domain-Events werden über die **Outbox** gepublished und sind reliable. Siehe Kapitel 8 für die Event-System-Rollen.
+Domain-Events werden über die **Transaction Outbox** gepublished: ein Service schreibt das Event in die `event_outbox` Tabelle innerhalb derselben DB-Transaktion. Der ARQ-Worker pollt die Outbox alle 5 Sekunden und published die Events auf den **EventBus**.
 
+Der **TriggerDispatcher** (`app/core/trigger_dispatcher.py`) abonniert den `*` Wildcard-Handler auf dem EventBus und evaluiert jedes eingehende Event. Bei einer Übereinstimmung mit einer `AutomationDefinition` (`trigger_type="event"`, `trigger_config.event_name` matcht) wird `run_automation` aufgerufen.
+
+**Flow:**
+```
+Service → enqueue_outbox_event() → event_outbox Tabelle
+                                         ↓ (commit)
+ARQ Worker (process_outbox_job, alle 5s)
+                                         ↓
+EventBus.publish_with_results(event_name, envelope)
+                                         ↓
+TriggerDispatcher._on_event(payload)
+                                         ↓
+DB-Query: AutomationDefinition WHERE trigger_type='event' AND trigger_config->>'event_name' = event_name
+                                         ↓
+run_automation(trigger_type="event", trigger_data=payload)
+```
+
+**Beispiel — Domain-Event in Automation umwandeln:**
 ```python
-# Plugin deklariert Events im Manifest
-manifest = PluginManifest(
-    name="my_plugin",
-    events=["contact.created", "contact.updated"],
-    ...
-)
+# AutomationDefinition erstellen
+POST /api/v1/automation/
+{
+    "name": "notify-on-contact-create",
+    "trigger_type": "event",
+    "trigger_config": {"event_name": "contact.created"},
+    "conditions": [],
+    "actions": [
+        {"type": "notification", "config": {"user_id": "...", "title": "Neuer Kontakt"}}
+    ]
+}
+```
 
-# Handler wird automatisch via on_activate registriert:
-async def on_contact_created(self, payload: dict[str, Any]) -> None:
-    """Reagiert auf contact.created Outbox-Event."""
-    contact_id = payload.get("contact_id")
-    # Business logic here
+**Beispiel — Plugin veröffentlicht Domain-Event:**
+```python
+from app.core.outbox import enqueue_outbox_event
+
+await enqueue_outbox_event(db, tenant_id, "contact.created", {
+    "contact_id": str(contact.id),
+    "tenant_id": str(tenant_id),
+})
+# Event wird beim Commit der Transaktion persistent.
+# Der Worker published es an den EventBus.
+# Der TriggerDispatcher findet passende Automations und führt sie aus.
 ```
 
 ### 10.2 UI-Event-Trigger (ephemeral)
 
-Flüchtige UI-Events (z.B. `ui.contact_selected`) laufen über den **EventBus** — nicht über die Outbox. Siehe Kapitel 18.
+UI-Events (`ui.*`) sind **ephemeral** — sie werden **nicht** in die Outbox geschrieben. Sie fließen direkt vom Frontend über WebSocket → EventBus → TriggerDispatcher.
 
-```python
-event_bus = get_event_bus()
-event_bus.subscribe("ui.contact_selected", self._on_contact_selected)
+Der TriggerDispatcher erkennt UI-Events am `ui.` Prefix und setzt `trigger_type="ui"` beim Dispatch. `AutomationDefinition`-Einträge mit `trigger_type="ui"` werden automatisch gematcht.
+
+**Flow:**
+```
+Frontend (WebSocket) → ws_helpers → EventBus.publish("ui.contact_selected", payload)
+                                         ↓
+TriggerDispatcher._on_event(payload)
+    → is_ui_event("ui.contact_selected") = True
+    → trigger_type = "ui"
+                                         ↓
+DB-Query: AutomationDefinition WHERE trigger_type='ui' AND trigger_config->>'event_name' = 'ui.contact_selected'
+                                         ↓
+run_automation(trigger_type="ui", trigger_data=payload)
 ```
 
-### 10.3 Cron-Trigger
+**⚠️ Kritische Regel:** UI-Events dürfen **niemals** über `enqueue_outbox_event()` gepublished werden. Verwende ausschließlich `event_bus.publish()`:
+```python
+from app.core.event_bus import get_event_bus
 
-Cron-Jobs werden im Manifest deklariert und vom Worker ausgeführt:
+# RICHTIG — ephemeral, nur EventBus
+event_bus = get_event_bus()
+await event_bus.publish("ui.contact_selected", {
+    "event_name": "ui.contact_selected",
+    "tenant_id": str(tenant_id),
+    "data": {"contact_id": str(contact_id)},
+})
 
+# FALSCH — würde UI-Event in Outbox persistieren
+# await enqueue_outbox_event(db, tenant_id, "ui.contact_selected", {...})  # ❌
+```
+
+**Beispiel — UI-Event-Automation erstellen:**
+```python
+POST /api/v1/automation/
+{
+    "name": "track-contact-selection",
+    "trigger_type": "ui",
+    "trigger_config": {"event_name": "ui.contact_selected"},
+    "conditions": [],
+    "actions": [
+        {"type": "api_call", "config": {"url": "https://analytics.example.com/track", "method": "POST"}}
+    ]
+}
+```
+
+### 10.3 Cron-Trigger (schedule)
+
+Cron-Jobs werden über `AutomationCronJob`-Einträge in der Datenbank verwaltet. Der ARQ-Worker führt `scheduler_tick` alle 5 Minuten aus, liest fällige Cron-Jobs und enqueued `run_automation` mit `trigger_type="scheduled"`.
+
+**Flow:**
+```
+ARQ Cron (alle 5min) → scheduler_tick(ctx)
+                                         ↓
+DB-Query: AutomationCronJob WHERE is_active=True AND next_run_at <= now()

+Der `TriggerDispatcher` (`app/core/trigger_dispatcher.py`) ist das zentrale Bindeglied zwischen EventBus und Automation-Engine. Er ersetzt frühere hardcodierte Event-Handler-Stubs (`on_contact_created` etc.) durch eine generische Wildcard-Subscription.
+
+**Registrierung:**
+- In `app/main.py` lifespan (API-Container)
+- In `app/core/worker.py` `on_startup` (Worker-Container)
+
+```python
+from app.core.trigger_dispatcher import register_trigger_dispatcher
+from app.core.event_bus import get_event_bus
+
+event_bus = get_event_bus()
+register_trigger_dispatcher(event_bus)
+# Dispatcher abonniert '*' auf dem EventBus
+```
+
+**Matching-Logik:**
+1. Jedes Event auf dem EventBus erreicht `_on_event(payload)`
+2. `event_name` wird aus `payload["event_name"]` extrahiert
+3. `ui.*` Prefix → `trigger_type="ui"`, sonst `trigger_type="event"`
+4. DB-Query: aktive `AutomationDefinition` mit passendem `trigger_type` und `trigger_config.event_name`
+5. Jede Match-Definition wird über `run_automation` ausgeführt
+
+**Wichtig:** Der Dispatcher ist **generisch** — es gibt keine hardcodierte Event-Liste. Jedes registrierte Outbox-Event kann eine Automation triggern, sobald eine `AutomationDefinition` mit passendem `trigger_config.event_name` existiert.
