## Title

    Proposed fix: [npm 12] 'npm vX does not support Node.js vY' after upgrading npm globally on older Node 22/24 minors or Node 20

## Body

    Recommended action: Pin npm to a version compatible with your Node (e.g. npm@11) in CI, or upgrade Node to a supported minor before upgrading npm. Avoid unpinned `npm i -g npm@latest` in CI.
    
    Option: Pin npm major to what the Node version supports [evidence: official_recommended_action]
    Applies when: See record scope.
    Steps:
    1. Replace `npm i -g npm@latest` with `npm i -g npm@11` (or the version bundled with your Node).
    2. Or upgrade Node to ^22.22.2, ^24.15.0 or >=26.
    Expected: Command proceeds without the error.
    
    Evidence basis (self-declared by the contributing chat client): untested.
