description: Programmatic extension points for customizing dependency resolution and installation behavior.
  `.pnpmfile.cjs` exposes lifecycle hooks (`readPackage`, `afterAllResolved`) that let projects rewrite
  package manifests before installation. The `pnpm` block in `package.json` adds `overrides`, `packageExtensions`,
  `patchedDependencies`, `peerDependencyRules`, and `neverBuiltDependencies` for fine-grained dependency
  control without forking packages.
