Fixes & Improvements
- Fixed synced all-day events generating phantom "event changed" messages in chat on every sync pass
- Fixed synced recurring event overrides being pruned as the sync window moved, causing old cancellations to "uncancel" and edits to "revert" in chat
- Fixed the "sync only future events" setting still syncing past occurrences of repeating events
- Fixed all-day recurring series triggering phantom chat updates after travelling to a different time zone
- Fixed typed-text locations on synced recurring event overrides generating phantom chat updates on every sync pass
