修正 AGC 测试与 tsconfig lib 不兼容的 Promise.withResolvers 用法

- 改动文件：apps/ai-game-creator-shell/tests/gameDistributionPublishPanel.test.tsx（仅此一个文件）
- 写法替换：把 `Promise.withResolvers<unknown>()` 换成本地手写 deferred（`let settlePending` + `new Promise((resolve) => { settlePending = resolve })`），resolve 仍由外部持有、promise 仍交回测试，与原 onResolve/onReject 语义一致（原 reject 未被使用）
- 为什么不改 tsconfig：`Promise.withResolvers` 需要 lib ES2024，而 apps/ai-game-creator-shell/tsconfig.json 是 target/lib ES2022；为单个测试把 lib 提到 ES2024 会改整个 AGC 客户端的编译目标与运行时假设，影响面远大于此处需求，故只在测试内手写等价 deferred
- 验证：npm run agc:typecheck 五步全 0（check:tests:types → tsc -p tsconfig.json → skill-pack:check → bundled-resources:check → check-config.mjs）
