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.
