- Install Node.js 20.x LTS from official NodeSource repository
- Install latest npm and configure with save-exact
- Install Yarn package manager (optional, configurable)
- Idempotent installation with version checking
- Adds npm global bin to system PATH
- Configurable version (LTS, major, or specific version)
- GPG-signed packages from official sources
- Support for custom npm global prefix
- Optional global npm package installation

Features:
- Removes old NodeSource repos before upgrade
- Adds NodeSource GPG key securely via HTTPS
- Creates npm global directory with proper permissions
- Template for /etc/profile.d/npm_global.sh
- Verification output showing installed versions

Variables:
- nodejs_version: "20.x" (default, can be 18.x, 22.x, or specific version)
- install_yarn: true (can be disabled)
- add_npm_to_path: true (adds npm bin to PATH)
