[Dependencies] Upgrade devDependencies, update eslint and jest configs, and add .nvmrc (#746)

1. Upgrade devDependencies to avoid issues with deprecated packages
2. Migrate eslint config from .eslintrc.cjs to eslint.config.cjs
3. Update Jest config to ignore examples
4. Add .nvmrc to use node version >= 24
