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

The `scorecard-reusable.yml` reusable requires the calling `analysis` job
to declare `security-events: write` and `id-token: write` — called-workflow
permissions are CAPPED by the caller's block (the reusable docstring
states this explicitly).

Without this, every Scorecard run silently fails with `startup_failure`
because ossf/scorecard-action cannot upload SARIF.

Estate-wide sweep tracked at hyperpolymath/standards#282; same pattern as
julia-professional-registry#19 (2026-05-27) and absolute-zero#68
(2026-05-30).
