Merge remote-tracking branch 'origin/main' into feature/claude-code-research

✅ Verified LEANN CLI works perfectly with Claude Code
✅ Added integration guide with working examples
✅ Documented simple workflow for immediate use

Key findings:
- No code changes needed
- Just need --recompute-embeddings flag
- Search, ask, and build all work
- Ready for Claude Code agents and workflows
