(Migrated from github.com)

Instead of full migration, sync only changed events since last run.

Requirements:

Use WebDAV sync tokens to detect changes
Only fetch/update changed objects
Much faster for large calendars with few changes
Maintain sync tokens in state file

Technical Details:

Use syncToken from calendar
On subsequent runs: Use syncToken to fetch only changes
tsdav's smartCollectionSync handles this internally

Related: Issue #4 (Bi-Directional Sync) - similar technology

Dependencies:

tsdav smartCollectionSync (see /docs/docs/smart calendar sync.md)

Estimated Effort: Medium (3-4 days)

Related to: DAV Migration CLI - Phase 2
