Infrastructure: Dependency & Supply Chain Hygiene

<audit_rules>

• You MUST verify that a lockfile (package-lock.json, yarn.lock, etc.) is present and its integrity matches the package manager specified in the project.
• You MUST flag any unused dependencies or dependencies that are duplicated across sub-workspaces.
• You MUST ensure strict separation of dependencies (production) and devDependencies (build/test tools).
• You MUST flag any dependency that has known critical or high security vulnerabilities (e.g., requiring an npm audit check).
• You MUST be highly suspicious of packages with post-install scripts or unexpected version bumps to prevent supply chain attacks.
• You MUST recommend version pinning (removing ^ or ~) for critical security or infrastructure packages. </audit_rules>
