Volta Rules

Enforce using volta install instead of npm install -g for all global CLI tools — ensures project-aware version resolution and clean tool management.

Enforce that nvm, fnm, n, and Volta are never installed simultaneously — only one Node.js version manager allowed to prevent PATH conflicts and version confusion.

Enforce Volta version pinning in all Node.js projects — pin Node, npm, and Yarn in package.json, use LTS for production, and maintain single source of truth for versions.
