- New ScheduleCache class: maintains today's full schedule locally
- CalendarBridgeClient.getDaySchedule(): fetch all slots for a date
- Scheduler now runs two intervals:
- Heartbeat (60s): existing slot execution flow (unchanged)
- Sync (5min): pulls full day schedule into local cache
- Exposes getScheduleCache() for tools and status reporting
This enables the plugin to detect slots assigned by other agents
between heartbeats and provides a complete local view of the schedule.
