ugcDiscovery.getMap/getUgcGameVariant typed AuthoringAsset but discovery returns AssetBase shape #33

Version: 1.0.14

UgcDiscoveryModule.getMap, getMapWithoutVersion, getUgcGameVariant, getUgcGameVariantWithoutVersion are all typed Promise<HaloApiResult<AuthoringAsset>>, but the discovery endpoint (https://discovery-infiniteugc.svc.halowaypoint.com/hi/{kind}/{id}[/versions/{ver}]) returns the AssetBase shape — PublicName, Files.{Prefix, FileRelativePaths}, AssetId, VersionId, etc.

AuthoringAsset is the authoring API response (https://authoring-infiniteugc.svc.halowaypoint.com/...) — different fields (CustomData, AssetHome, IsCurrentlyBeingEdited, ...) and no PublicName/Files.

Repro:

const c = new HaloInfiniteClient({ spartanToken });
const r = await c.ugcDiscovery.getMapWithoutVersion('e859cf75-9b8a-429a-91be-2376681c8537');
r.result.PublicName;  // TS2339 — but the runtime object has it
r.result.Files;       // TS2339 — same

Fix: change the return types to HaloApiResult<MapAsset> / HaloApiResult<GameVariantAsset> (or AssetBase).

Found while wiring grunt into filmshell's worker — the cast is contained there for now.
