// The @local-studio/agent-runtime package (services/agent-runtime) ships raw
// .ts and is consumed via a file: symlink, so its sources resolve external
// deps (effect, ws, the pi SDK) from their REAL path under services/ — where
// no node_modules exists on the walk-up. Bridge services/node_modules to
// frontend/node_modules so every resolver (tsc, bun, webpack, turbopack,
// Node) finds the exact same dependency instances the frontend uses.
//
// Ran from frontend/ as part of postinstall.
