- 3-stage: validate → dry-run → deploy-migration
- validate: prisma format check, client generation verification
- dry-run: MySQL service container, db push + migrate deploy + status
- deploy-migration: manual trigger, SSH migrate deploy with pre/post status
- Triggered on schema.prisma or migrations/** changes
