Add workflow system that lets users describe automations in natural
language through the same input field. The server LLM classifies
input as either an immediate goal or a workflow rule, then:
- Parses workflow descriptions into structured trigger conditions
- Stores workflows per-user in Postgres
- Syncs workflows to device via WebSocket
- NotificationListenerService monitors notifications and triggers
matching workflows as agent goals
Also cleans up overlay text and adds network security config.
