Add agent runtime DB schemas and expand shared types

New schemas: agent_runtime_state, agent_wakeup_requests,
heartbeat_run_events. New migrations for runtime tables. Expand
heartbeat types with run events, wakeup reasons, and adapter state.
Add live event types. Update agent schema and shared constants.
