// Applies patches/ during the root postinstall.
//
// patch-package is a root devDependency, so `npm ci --workspace <name>` and
// `npm ci --omit=dev` install a tree without it while still running the root
// postinstall. Failing there would break install modes that work on main, so a
// missing patch-package is reported and skipped; a patch that exists but no
// longer applies still fails the install via --error-on-fail.
//
// Skipping is safe because those trees are not what ships: every release and CI
// lane runs a plain root `npm ci`, and an unpatched tree turns
// packages/runtime/src/__tests__/model-factory-tool-call-index.test.ts red.
