## Summary
- **Doc review:** Reviewed `gandi-operations.md` — added `last-reviewed` frontmatter, verified all wiki-links, confirmed Pulumi state has no drift
- **Gandi reference fix:** Added missing `cv.eblu.me` CNAME row to `gandi.md` DNS records table (was present in Pulumi but undocumented)
- **Pulumi comment fix:** Updated stale `README.md` reference in `__main__.py` to point to `docs/how-to/gandi-operations.md`
- **How-to reorg:** Moved 14 how-to guides into 3 subdirectories (`deployment/`, `configuration/`, `operations/`), collapsed the Documentation and Database index sections into Configuration and Operations respectively
## Verification
- `docs-check-links` — all 180 wiki-links valid
- `docs-check-filenames` — all 90 filenames unique
- `dns-preview` — 5 resources unchanged, no drift
- All pre-commit hooks pass
## Test plan
- [ ] Verify docs site builds correctly with new paths
- [ ] Spot-check a few wiki-links from other pages to moved how-to guides
