migration-review

Run db-guard's MIGRATION SAFETY REVIEW output block (in agents/db-guard.md, co-loaded with this fork) checkpoint by checkpoint — GO / NO-GO per checkpoint; the checklist lives there, not here (round-31: it was restated near-verbatim, unlike the sibling fork-skills' pointer style). One checkpoint that block lacks, add it: RENAME RISK — is the old name still referenced in code or queries?

Final output: GO / NO-GO | risk summary | required steps before applying
