feat: add Node.js version management

- Add .nvmrc for nvm users (22.12.0)
- Add .tool-versions for asdf users (22.12.0)
- Add engines field to package.json to enforce Node >=22 <23
- Specify Yarn >=4.0.0 as required package manager

This provides clear Node.js version requirements for local development,
aligning with the CI/CD configuration (Node 22.x).
