The 30-day retention window for soft-deleted annotations was a package
const; move it behind the registry so it can be tuned live.
annotations.go:
- AnnotationService gains an optional *database.SettingsRegistry and a
tombstoneTTL() helper. The skip-resurrect checks and the purge cutoff
now call it instead of reading the TombstoneTTL const directly.
- Add ActiveTombstoneTTL() so callers outside the sync package can
compute cutoffs consistently with the service.
- The package-level TombstoneTTL const is retained as the fallback for
tests / unwired code paths.
kobo.go, koreader.go:
- The per-book tombstone sweep cutoff now uses
h.annotationSvc.ActiveTombstoneTTL() instead of the wsync.TombstoneTTL
const, so both the service and the handlers honor the configured TTL.
