The vector scanner crashed when encountering notes without a 'modified' field,
causing KeyError and preventing initial sync from completing.
Changes:
- Use dict.get() with fallback value (0) instead of direct key access
- Log warnings for notes missing 'modified' field
- Apply fix to both initial sync and incremental sync code paths
This ensures the scanner continues processing all notes even if some have
missing metadata fields, preventing scanner crashes that could affect
deployment readiness.
Fixes: Notes without 'modified' field causing scanner crash and readiness check failure
