📝 Walkthrough

Walkthrough

The calendar entity documentation now defines an optional CalendarEvent.status field with confirmed and tentative values. It also documents unset-status semantics and excludes cancelled events from calendar results.

This documentation-only change adds the CalendarEvent status description and has no product or runtime impact; only a minor RFC 5545 capitalization cleanup remains, so it is otherwise merge-ready.

distinguish RFC 5545 semantics from provider adapter behavior: avoid claiming
the standard requires cancelled events to remain stored, and describe Google
Calendar cancellation filtering only as behavior of the integration or adapter.
Preserve the documented status mappings while noting that cancelled resources
may be returned by Google Calendar get and incremental sync operations.
