     * Creates a calendar event in Sunsama and optionally syncs it to an external
     * calendar service (e.g., Google Calendar). The event can be linked to an
     * existing task via the `seedTaskId` option.

     * @param title - The title of the calendar event
     * @param startDate - Start date/time as Date object or ISO string
     * @param endDate - End date/time as Date object or ISO string
     * @param options - Additional event properties
     * @returns The created calendar event result with success status
     * @throws SunsamaAuthError if not authenticated
     * @throws SunsamaValidationError if start date is after end date
     * @throws SunsamaError if unable to determine user context
