Regenerate doc snippet and llm-docs for new exports

The build.sh check that detects uncommitted changes was failing because
01-types-implement-interface.out didn't reflect the new getTypeName and
personClassMap exports, and llm-docs/guides/node-spec.md was using a
different list-bullet style than the rest of llm-docs.

 Grats generates two exports in `schema.ts` that power this pattern:
 
-- **`nodeClassMap`** — An object mapping GraphQL typenames to their class constructors for every type that implements the `Node` interface. Grats generates one of these maps per interface in your schema.
-- **`getTypeName`** — A function that returns the GraphQL typename for any class instance, using the same prototype-chain resolution that GraphQL uses internally. This lets you encode global IDs without defining `__typename` on your classes.
