## Title

    Proposed fix: [Corepack] 'Cannot find matching keyid' when installing pnpm/yarn via Corepack after npm registry signing key rotation

## Body

    Recommended action: Upgrade Corepack itself (npm install -g corepack@latest, >=0.31.0) or use a Node.js release that bundles a newer Corepack.
    
    Fix: Upgrade Corepack to >=0.31.0 [evidence: released_fix]
    Applies when: Any environment where Corepack fails with keyid mismatch
    Steps:
    1. npm install -g corepack@latest
    2. corepack enable
    3. re-run the package manager command
    Expected: Signature verification succeeds with updated keys
    
    Option: Temporarily disable integrity keys [evidence: documented_workaround]
    Applies when: When upgrading Corepack is not possible
    Steps:
    1. export COREPACK_INTEGRITY_KEYS=0
    Expected: Corepack skips signature verification
