Stream Unreal - docs orchestrator for Unreal Engine

Chat only. There is no Stream Video or Stream Feeds SDK for Unreal (/video/docs/unreal and the Feeds Unreal index both 404). If the user asks for calling or feeds in Unreal, say so up front and offer the alternatives (a platform SDK on a companion mobile app, or the REST/server API) rather than inventing an API.

The SDK is in beta. IsBetaVersion: true in the .uplugin; the surface can change between releases, and C++ and Blueprint coverage differ per operation. State this whenever the user pins a version or plans an upgrade.

This skill orchestrates: it gates the request against engine support and feature support, routes to the exact docs page, fetches it live, and applies it - while carrying the curated Unreal-specific knowledge the docs do not have (the ApiKey/BeginPlay ordering trap, the UMG widget layer, cooking, and the per-platform config that decides whether a packaged build is usable).

Rules (read once per session): RULES.md - non-negotiable rules + Unreal pitfalls. Read before writing any code.

Step 0: Three gates, before any code

Resolve all three from the user's words plus a read-only probe. Each one can change the answer from "here is the code" to "that is not possible" - so none of them is optional, and none of them belongs in a compile error later.

Gate 1: engine version (picks the release asset, or stops the task)
