chore(ci): convert hypatia-scan.yml to thin wrapper of standards reusable

Replaces ~416 lines of duplicated Hypatia scan plumbing with a 29-line
wrapper calling hyperpolymath/standards/.github/workflows/hypatia-scan-reusable.yml
at SHA 2569c10e831e293f9dd6580d82a494aca039deee (standards#191 HEAD).

Behaviour-preserving: same triggers, same concurrency group, same
permissions, same secrets passthrough.

Refs standards#191.

-
-          | Severity | Count |

-          | Critical | ${{ steps.scan.outputs.critical }} |
-          | High     | ${{ steps.scan.outputs.high }} |
-          | Medium   | ${{ steps.scan.outputs.medium }} |
-          | **Total**| ${{ steps.scan.outputs.findings_count }} |
-
-          ## Next Steps
-
-          1. Review findings in the artifact: hypatia-findings.json
-          2. Auto-fixable issues will be addressed by robot-repo-automaton (Phase 3)
-          3. Manual review required for complex issues
-
-          ## Learning
-
-          These findings feed Hypatia's learning engine to improve future rules.
