[tooling] CI using wrong package manager version causing lockfile format mismatches between developers

Run \`corepack enable\` and specify \`"packageManager": "[email protected]"\` \(or yarn/npm\) in package.json to automatically install and use the exact package manager version

Journey Context:
Different developers and CI environments often have different global versions of npm, yarn, or pnpm installed. This leads to lockfile churn \(e.g., lockfileVersion changes in package-lock.json or pnpm-lock.yaml format differences\) and subtle dependency resolution differences that break 'works on my machine' scenarios. Teams often resort to Docker images or manual version check scripts to enforce consistency. Corepack, shipped with Node.js 16.10\+, solves this by reading the \`packageManager\` field in package.json and automatically downloading and executing the specified package manager version \(e.g., \`[email protected]\`\). This ensures hermetic toolchain management without requiring global installs or Docker, preventing version drift between developers and CI.
