and rate limiting +- **Caching**: Leverages existing content-fetch caching +- **Resource cleanup**: Proper worker shutdown and cleanup + +## Testing Strategy + +### Integration Tests + +The implementation includes comprehensive integration tests covering: + +- **End-to-end workflow**: Link saving → processing → completion +- **Content type handling**: HTML, PDF, email, RSS, YouTube +-
