fix(sdk): inject assertions into Creator-loaded contract harness

 `GameEntry.resolveSeatCount` 只接收真实房间的 `roomtype`，预检只检查该方法存在；
 GameHost 在进房边界验证返回值是正整数并与服务器座位数组长度相同。
-`assertGameContract(entry, samples)` 的每个样本由游戏提供 `roomtype`、`expectedSeatCount`
+`assertGameContract(entry, samples, assert)` 的 `assert` 由测试调用方从 `node:assert/strict`

 和对应的 `makeHost` 工厂，不要求游戏支持框架虚构的房间配置。
 
 远程地址唯一取自 `data.urlserver`。配置请求使用空 body 的 POST，沿用无条件 `?` 缓存参数拼接。
