Generate a Node.js package map at `node_modules/.package-map.json` on every isolated or hoisted install, including under the global virtual store, so that third-party tooling can start experimenting with package maps. The file is serialized compactly. Two settings control how the map is consumed: - `node-experimental-package-map` (default: off): inject `--experimental-package-map` into `NODE_OPTIONS` for the Node.js scripts pnpm runs — dependency lifecycle scripts, `pnpm exec`, and `pnpm run` (including recursive runs). - `node-package-map-type` (`standard` | `loose`): choose between a strict map and one that tolerates hoisting-like access. Covered by both the pnpm CLI and the pacquet (Rust) implementation. --------- Co-authored-by: Zoltan Kochan <z@kochan.io>
