ci(scorecard): add job-level permissions for reusable workflow (#34)

## Summary
- Add `permissions: { security-events: write, id-token: write }` to
`jobs.analysis` so the called scorecard reusable can upload SARIF.
- Without job-level overrides the caller's `permissions: read-all` caps
the reusable and `ossf/scorecard-action` silently `startup_failure`s.
