Fix CI: add --experimental-test-module-mocks, require Node >= 22

- CI step for src/**/*.test.ts was missing --experimental-test-module-mocks,
  causing tier-status.test.ts and provision.test.ts to fail (pre-existing)
- Update matrix to [22, 24] since mock.module needs Node >= 22.3 and
  @noble/curves v2 needs Node >= 20.19
- Update engines to >=22 in both packages
