Calendar Brief

• Use list_calendars if the target calendar is not obvious.
• Use get_events with a bounded time range.
• Summaries should lead with the next meetings, then conflicts, then missing prep or travel concerns.
• If a window contains no events, say so plainly.
• Do not imply calendar creation or mutation support in v1.
