Problem description

When using pnpm, forge requires node-linker=hoisted in the project's .npmrc configuration. If the project is a monorepo with electorn inside e.g root/app, node-linker=hoisted means all node-modules are hoisted into the root/node_modules.
However electron-forge expects the node-modules to be present in the apps-root (root/app/node_modules) and therewith wont resolve native modules during build...

Proposed solution

Support linked node-modules to be compatible with pnpm stores

Seems like a main blocker is the usage of flora-colossus, which expects the modules to exist next to the package.json. Otherwise it'll throw the error Failed to locate module "${moduleName}" from "${modulePath}" - view source
