feat: complete SDK dispatch - all methods implemented (32-41)

- DocMemory: Insert/Remove/Stats dispatch (32-34)
- Knowledge: Add/List dispatch (35-36)
- LLM: CurrentSource dispatch (37)
- Social: GetTrait/GetRelations/ListPersons dispatch (38-40)
- TextMemory: Append dispatch (41)
- EventBus: subscribe stub (not wired for external plugins)
- All bridge template stubs replaced with real dispatch calls
