feat: schedule cache, workflow-aligned prompts, dispatchInbound wakeup

1. ScheduleCache: local cache of today's schedule, synced every 5 min
   from HF backend via new getDaySchedule() API

2. Wakeup prompts updated to reference daily-routine skill workflows
   (task-handson, plan-schedule, slot-complete)

3. Agent wakeup via dispatchInboundMessageWithDispatcher (in-process)
   - Same mechanism as Discord plugin
   - Creates unique session per slot: agent:{agentId}:hf-calendar:slot-{slotId}
   - No WebSocket, CLI, or cron dependency
   - Verified working on test environment
