- computeDiff classifies files into added/modified/deleted/unchanged buckets
- Only changed and new files are parsed and re-embedded on re-runs
- Deleted files removed atomically from DB
- Progress counts all files including unchanged for accurate reporting
- ~20x speedup for re-indexing large repositories with few changes
