Backend: generate EventException on create/update when skip_holidays or recurrence changes; emit RecurrenceException (EXDATE) with exact occurrence start time (UTC)
API: return master events with RecurrenceRule + RecurrenceException
Frontend: map RecurrenceException → recurrenceException; ensure SkipHolidays instances never render on holidays; place TentTree icon (black) next to main event icon via template
Docs: update README and Copilot instructions for recurrence/holiday behavior
Cleanup: remove dataSource and debug console logs
Replace placeholder clone URL with actual repo URL:

Add first-run step to initialize the database using the one-shot script:
python server/initialize_database.py
Mention initialize_database.py in project structure
Add a one-shot DB init command to the “Database Management” section
Update Copilot instructions:
Prefer initialize_database.py for local dev (migrations + defaults + academic periods)
Note legacy init scripts were removed; use Alembic + initialize_database.py going forward
No runtime/code changes; documentation only
