Usage

• Always pass an Olson timezone (Europe/Berlin, America/New_York) when creating or editing events. Ask the user if unclear.
• Run calendar-cli calendars first to discover available calendar names. Calendar names are resolved case-insensitively.
• list, show, and search do not sync by default (fast, uses local cache). Pass --sync to pull remote changes first.
• new, edit, and delete always sync after the operation.
• list shows at most 50 events by default and truncates descriptions. Use show <uid> to get full details of a specific event.
