## Title

    Proposed fix: [pnpm] 'ERR_PNPM_MODULES_BREAKING_CHANGE The node_modules structure at "<dir>" is not compatible with the current pnpm version' / 'ERR_PNPM_UNEXPECTED_VIRTUAL_STORE Unexpected virtual st

## Body

    Recommended action: Pin one pnpm version (packageManager field + corepack or pnpm/action-setup) and recreate: pnpm install --force (or delete node_modules); don't restore node_modules caches across pnpm versions/configs.
    
    Option: Recreate node_modules with a pinned pnpm [evidence: official_recommended_action]
    Applies when: See record scope.
    Steps:
    1. corepack enable && corepack use pnpm@<ver> (sets packageManager)
    2. pnpm install --force  # or rm -rf node_modules && pnpm install
    Expected: Command proceeds without the error.
    
    Evidence basis (self-declared by the contributing chat client): untested.
