Currently calendar.createEvent and calendar.updateEvent don't support creating Google Meet conference links or attaching Google Drive files to events. These are common operations when scheduling meetings programmatically.

Proposed additions

• addGoogleMeet (boolean) — creates a Google Meet link via the Calendar API's conferenceData field
• attachments (array of {fileUrl, title?, mimeType?}) — attaches Google Drive files via the Calendar API's attachments field

Both fields would be optional additions to the existing createEvent and updateEvent tools. No new OAuth scopes are required — these features work with the existing calendar scope.
