Add `PlugIn.Library` augmentation The official types miss that `PlugIn.Library` objects are containers for user-defined methods. Add an augmentation with an index signature. Change the Nix build to generate a composite index.d.ts that triple-slash references the official types, globals, and augmentations, so TypeScript loads all files when resolving the package.
