fix: resolve npm audit high severity vulnerabilities (#1347)

- Upgrade fast-xml-parser to 5.10.1 (fixes GHSA-8r6m-32jq-jx6q)
- Add package.json override to force brace-expansion >=5.0.8 across
  all transitive dependencies (fixes GHSA-mh99-v99m-4gvg) without
  downgrading jest/ts-jest
- Refresh .licenses/npm cache to match updated dependency tree
- Rebuild dist/setup and dist/cache-save

npm audit now reports 0 vulnerabilities. Pre-existing test suite
failures (7 suites, ESM/jest teardown issue) verified unrelated to
this change - identical on unmodified main with node 24.
