feat: Add 10 new low-FP checks across Docker, CI, Dependencies

Docker (5 new):
- docker-017: FROM with :latest tag (security risk)
- docker-018: No HEALTHCHECK (reliability)
- docker-019: Running as root (security)
- docker-020: ENV without quotes (stability)
- docker-021: WORKDIR with relative path (predictability)

CI (3 new):
- ci-010: Unpinned actions @V3 instead of SHA (34% incidents)
- ci-011: No permissions defined (least privilege)
- ci-012: Hardcoded secrets in workflow (security)

Dependencies (2 new):
- deps-010: Missing package-lock.json (reproducibility)
- deps-011: Missing engines in package.json (compatibility)

All checks have low false-positive risk and include fix suggestions.
