[2026-10-28] v3.9.13

C# constructors with default parameters can be called from JS without them, and generic types, extension methods and array parameters now typecheck the way they already ran. On WebGL every app's onPlay and onStop run, and useEventSync reports a C# event or property that throws instead of hiding it.

• new calls a C# constructor whose trailing parameters have defaults, with them left out (#146)
• On WebGL, onPlay and onStop run for a strict bundle, as every scaffolded app's is (#145)
• Generated types: a generic class is callable with its type arguments, as List(Int32) (#148)
• Generated types: an extension method keeps its this parameter on its static class (#149)
• Generated types: an array parameter takes a JS array or typed array (#150)
• useEventSync logs an event accessor or getter that throws, and warns only about a missing event (#152)
• compute.struct's stride is the HLSL struct's size, with no rounding to 16 bytes
• New projects get onejs-react 0.4.3, onejs-unity 0.11.1 and ojplay 0.12.2
