BetterIk/Skeleton/AssemblyInfo.cs

AssemblyInfo for the BetterIk.Skeleton folder, enabling nullable annotations and containing comments about engine-agnostic bone-walking logic and build targets.

#nullable enable annotations

// Engine-agnostic bone-walking logic. No Sandbox/Editor references allowed in this folder:
// these sources also compile in the plain net8.0 dev harness (dev/BetterIk.Dev.csproj)
// so the chain resolver can be unit-tested against a fake bone graph without the editor.
