Stalwart's CalendarEvent/query ignores Task-type objects and does not
support the 'types' filter (returns unsupportedFilter error). This
caused tasks both locally created and from external clients like
Thunderbird to disappear on reload.
Root causes:
- CalendarEvent/query only returns @type:'Event' objects on Stalwart,
so tasks were invisible to the query endpoint.
- CALENDAR_EVENT_PROPERTIES lacked Task-specific fields (due, progress,
progressUpdated, priority), causing garbled data when tasks were
fetched with Event properties (e.g. utcStart:'32548-12-04T15:30:07Z').
Changes:
- Add CALENDAR_TASK_PROPERTIES with Task-specific fields (due, progress,
progressUpdated, priority).
- Rewrite getCalendarTasks() to first try CalendarEvent/query with
types:['Task'] filter, then fall back to CalendarEvent/get ids:null
which returns all calendar objects regardless of @type per JMAP spec.
- Rewrite createCalendarTask() to fetch back created tasks using
CALENDAR_TASK_PROPERTIES instead of piggybacking on createCalendarEvent.
- Add comprehensive debug logging throughout the task fetch/create flow
(TaskStore, JMAP client) visible when Debug Mode is enabled.
- Add 'types' field to CalendarEventFilter interface.
