addToCalendar

Add a single event to the user's Google Calendar and show it in chat, with a link back to the real event once created. Use when the user asks to add/save something specific to their calendar (an event you found via findRealLinks, a meeting, a deadline) — not for anything recurring (one-shot events only); use getCalendarEvents instead if the user's asking what's already on their calendar rather than adding something. The first use of ANY calendar tool in a session needs the user to grant access via a one-tap connect card rendered in chat — that access is session-only (never stored beyond the current tab) and shared with getCalendarEvents (one grant covers both), so don't imply it 'remembers' this for later; if the user wants standing calendar access that works across sessions, tell them that's not supported yet rather than guessing. Always pass a real timeZone (an IANA name like 'Europe/Paris') — use the one from the user's own message context block, don't guess or default to UTC.
