**用途**
- 转发 `UnityPlayer.dll` 实际导入的少量 `version.dll` 导出函数
- 等待 IL2CPP 运行时初始化稳定
- 运行时 hook `Stage.NetworkUtil.GetSchemeType()`强制返回 `0`
- 可选地 hook `Stage.NetworkUtil.GetSchemeType()`在需要时强制切到 `http`
- 支持通过 `config.json` 覆盖 `api_url``asset_url`
**目录结构**
@@ -17,6 +17,7 @@
- `GameAssembly.dll` 出现时,IL2CPP runtime 可能还不能安全访问,因此 hook 线程会额外等待一小段时间
- 运行时日志会写到游戏目录下的 `cgss-http-hook.log`
- 生成的 DLL 包含 Windows 版本资源,定义在 `src/version.rc`
- 支持通过 `force_http` 控制是否 hook scheme,默认 `true`
- `config.json` 中的 URL 会自动规范化:若写了 `http://``https://` 会自动去掉,若末尾缺少 `/` 会自动补上

```json
{
"force_http": true,
"api_url": "apis.game.starlight-stage.jp/",
"asset_url": "asset-starlight-stage.akamaized.net/"
}

字段说明:
- `force_http`:是否强制将 scheme 改成 `http`。默认 `true`
- `api_url`:API 主机名,按原始字段格式填写,不带 scheme
- `asset_url`:资源主机名,按原始字段格式填写,不带 scheme
