Release 1.1.2 — the default path works end to end

Fix release for 1.1.1: the minimal path end to end, engine commands that
run on Godot, Unity and Unreal, hook warnings you can see, and verdicts
that say when they could not check. Details in CHANGELOG.md; upgrade
steps in UPGRADING.md (v1.1.1 → v1.1.2).

Fixes #67
Fixes #131

+- Guide language decisions: GDScript vs C# vs GDExtension (C/C++/Rust) per feature — GDScript has no build step and the tightest editor integration; C# is faster for CPU-heavy loops and needs the .NET build of the editor and export templates; GDExtension gives native speed at the cost of a compiled library per platform
