feat(radar): stable catalog export workflow with provenance (#10826)

Passo 10 of the Radar go-live: publish the OmniRoute catalog export the Radar
server consumes to a stable URL, so the 1 GB-RAM private server pulls it via
RADAR_EXPORT_URL instead of depending on the deploy-time snapshot.

- scripts/release/radar-export.mjs: emits {geradoEm, budgets, totais, registry,
  provenance} from the catalog config modules. Provenance (sourceCommit,
  sourceRef, runUrl, generatedBy) is never fabricated — unknown fields stay null.
- .github/workflows/radar-export.yml: on main catalog changes / manual dispatch /
  weekly, generates the export and clobbers the stable 'radar-export-latest'
  release asset (gh release, GH_TOKEN — checkout persist-credentials:false).
- tests/unit/radar-export.test.mjs: consumer contract (budgets[] non-empty) +
  provenance null-when-unknown + GitHub-env reflection.

Stable URL for RADAR_EXPORT_URL:
https://github.com/diegosouzapw/OmniRoute/releases/download/radar-export-latest/export-omniroute.json

Re-baselines zizmorFindings 190->192 (+2 unpinned-uses @vN, the repo-wide
deliberate convention; artipacked auto-fixed).
