Fix npm audit vulnerabilities and unblock Renovate lockfile maintenance

Sets minimumReleaseAge to null for lockFileMaintenance, matching the
config already proven in tanem/react-svg. The repo-wide 3-day release
soak was also applying to weekly lock refreshes, and since a full
refresh always pulls in something published within 3 days, the
resulting PR's renovate/stability-days check could never pass -
deadlocking #2929 since 2025-11-24 and leaving 23 transitive dev
dependency alerts unaddressed.

Also:
- Bump @babel/core to 7.29.7 (pinned exact, so the lockfile refresh
  alone couldn't reach the patched version).
- Add an override pinning brace-expansion to ^5.0.8, fixing
  GHSA-mh99-v99m-4gvg (a DoS newly published 2026-07-24) in nested
  copies that eslint/jest/ts-jest otherwise keep on 1.x/2.x.
- Migrate examples/react-router-v6 to react-router-dom 7.18.2,
  fixing GHSA-jjmj-jmhj-qwj2 (open redirect/XSS), which has no fix in
  the 6.x line. Renamed to examples/react-router since the version
  is no longer relevant. Verified with a headless browser that
  navigation and the progress bar animation still work correctly.
