- Strengthen extraction prompt to always generate 2-4 tags per memory
- Add Phase 2b: Retroactive Tagging to sleep cycle for untagged memories
- Include 'skipped' memories in extraction pipeline (imported memories)
- Add listUntaggedMemories() helper to neo4j-client
- Add extractTagsOnly() lightweight prompt for tag-only extraction
- Add CLI display for Phase 2b stats
Fixes: 79% of memories had zero tags due to weak prompt guidance
and imported memories never going through extraction.
