Add C# WebAssembly Translator and JavaScript Method Export Generator

[daosgava]

Description

Add support for generating C# WebAssembly bindings and JavaScript method names.

Details

• Introduced a new translator class CSharpWasm to generate C# bindings compatible with WebAssembly.
• Implemented logic to filter and convert only primitive-type functions into valid C# partial methods.
• Outputs SplashKit.Generated.cs, which includes method signatures for WASM interop.
• Added generation of splashKitMethods.generated.js, which exports a list of available function names in snake_case format.
• Both files are placed in generated/csharpwasm/ as part of the build output.

Command

docker compose run --rm headerdoc csharpwasm

Notes

Once the translator is fetched as a submodule into splashkit-core, it should generate the files in generated/csharpwasm.

Sample of SplashKit.Generated.cs

using System.Runtime.InteropServices.JavaScript;

namespace SplashKitSDK
{
    public partial class SplashKit
    {
        [JSImport("SplashKitBackendWASM.free_all_animation_scripts", "main.js")]
        public static partial void FreeAllAnimationScripts();

        [JSImport("SplashKitBackendWASM.free_animation_script", "main.js")]
        public static partial void FreeAnimationScript(string name);

        [JSImport("SplashKitBackendWASM.has_animation_script", "main.js")]
        public static partial bool HasAnimationScript(string name);

        [JSImport("SplashKitBackendWASM.audio_ready", "main.js")]
        public static partial bool AudioReady();
        ...

Sample of splashKitMethods.generated.js

const methods = `
  accept_all_new_connections,
  accept_new_connection,
  add_column,
  add_column_relative,
  alpha_of,
  angle_between,
  animation_count,
  animation_current_cell,
  animation_current_vector,
...

The two generated files need to be copied into the SplashKitOnline repo.
