Disposition per group, keyed as `xantham.json` spells them: npm name for a dependency, `typescript/lib` for the compiler lib.

The compiler's `lib` option, as `tsconfig.json` spells it (`["esnext"]`). `None` is the compiler's default, which includes the DOM. A global type library that redeclares DOM names (`@cloudflare/workers-types`) must set this to what its README prescribes: with the DOM loaded, every such name merges with the lib's declaration, is grouped as the compiler lib by its first declaration, and is not the package's to harvest.

Overrides the F# module name otherwise derived from the package name.

The F# namespace a package family is written under. The entry package takes the namespace itself, and each group named under `groups` takes `.`: `FSharp.CloudEdge` names `@cloudedge/agents` as `FSharp.CloudEdge.Agents`. A dependency the configuration leaves unnamed keeps its derived module. Both sides of a `reference` configure the same namespace. The referencing run templates a name the referenced run has to produce, and `GE004` records each group named this way.

Overrides the npm package the generated `[]` attributes name. `None` derives it from the package name (`GeneratorConfig.runtimePackage`), which is right for every package that ships its own JavaScript and for the DefinitelyTyped naming convention. It is the escape hatch for the packages the convention cannot describe: a `@types/*` package whose runtime is named something else entirely, and a types-only package published outside DefinitelyTyped.
