chore: migrate to Node 24 with corepack for npm version management

- Update Node.js version from 22 to 24 in .nvmrc
- Add packageManager field to enforce npm 10.9.0 via corepack
- Enable corepack in all CI workflows to ensure consistent npm version
- Update developer setup instructions in README

This fixes lockfile sync issues between local development and CI by ensuring
all developers use the same npm version (10.9.0) automatically through corepack.
