chore: add Node.js 24 support, drop Node.js 18

- Update package.json engines to support Node.js ^22 and ^24
- Update .nvmrc to Node.js 24.14.1 for development
- Update Dockerfile to use Node.js 24-alpine
- Update @types/node to 22.19.15 for type compatibility
- Node.js 18 is EOL and no longer supported per project policy
- Node.js 24 is now Active LTS and fully supported

Closes #389
Closes #390
