- Add _merge_results() to preserve data from inactive sources when reprocessing CVEs incrementally, deduplicating by hash/url and combining source strings
- Add _accumulate_stats() to correctly count per-source statistics for both skipped and reprocessed entries
- Add retry with exponential backoff to Ubuntu API client, handling 429 rate-limiting and transient failures (3 attempts, configurable base delay)
- Refactor extract_from_ubuntu_response() to use shared _process_url() helper, removing duplicated hash/PR extraction logic
- Add tests for retry exhaustion and 429 recovery
