Update CI and runtime configuration

- Add .npmrc with legacy-peer-deps=true (TS 6 peer dep workaround)
- Update GitHub Actions matrix: Node 22 + 24 (drop Node 20)
- Use --legacy-peer-deps in CI npm install step
- Bump node engine to >=22 (Node 22 LTS)
- Replace ts-jest ignoreDeprecations with diagnostics: false
  (tsc handles type checking, ts-jest only transpiles)
