Event Querying With Date Range Filtering

** - A CalDAV MCP server to expose calendar operations as tools for AI assistants.

Unique: Uses ts-caldav's getEvents() with CalDAV REPORT requests for server-side date filtering, reducing payload size compared to fetching all events and filtering client-side. Zod validates ISO 8601 date strings before passing to CalDAV client.

vs others: More efficient than REST APIs that require fetching all events because CalDAV's REPORT method performs server-side filtering, reducing bandwidth and latency for large calendars.
