feat: sync recurring tasks to Google Calendar as recurring events
Scheduled-based recurring tasks now sync to Google Calendar as native recurring events with RRULE support instead of single events. - Add rruleConverter utility to convert TaskNotes RRULE format to Google Calendar recurrence array format (RRULE + EXDATE entries) - Extend GoogleCalendarService.createEvent/updateEvent with recurrence parameter support - Add shouldSyncAsRecurring() helper to detect eligible recurring tasks - Update taskToCalendarEvent() to include recurrence data with DTSTART extraction and EXDATE generation for completed/skipped instances - Modify completeTaskInCalendar() to update EXDATE instead of adding checkmark for recurring tasks - Add updateRecurringEventExdates() for efficient instance exclusion Completion-based recurring tasks (recurrence_anchor='completion') continue to sync as single events since their DTSTART shifts on each completion, which doesn't map well to Google Calendar.

- Default reminder setting for popup notifications
|

- Bulk sync and unlink actions in settings
|

- Task-event linking stored in frontmatter (`googleCalendarEventId`)
|

- Recurring tasks with scheduled anchor sync as Google Calendar recurring events with RRULE

- Completed/skipped instances automatically excluded via EXDATE

- Thanks to @someromans and @Leonard-44 for requesting this feature, and @dmantisk, @farangkao, @rayvermey, and @rdpr for their input
