godot-wechat-minigame-adapter

Port a fresh official Godot 4.x checkout to WeChat Mini Game / 微信小游戏, or refresh an existing port after upstream sync. Use when adapting `platform/web`, replaying proven WeChat runtime patches, auditing moved files across Godot versions, or fixing WeChat-specific runtime issues such as WXMEMFS persistence, `wx.request` chunk handling, `wasm_simd` gating, `wx.getWindowInfo`, `wx.showKeyboard`, `.wasm.br` loading, and `wx.exitMiniProgram`.
