Subject: [PATCH] test(ai): add LLMSession/AIRuntime smoke tests (no real
 inference)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

iOS Simulator sandbox 看不到 host ~/tiji-models;Mac Designed for iPad
卡 code signing。真实推理验证由 DebugAIRunner 手动跑,结果记 W2 retro。
W3 把核心 LLM 接口拆独立 SPM target 后,可在 Mac 原生跑真实推理。

烟测覆盖:
- TokenChunk 值字段
- AIRuntimeError 3 case 都有 errorDescription
- AIRuntime actor status 可异步读取

+/// LLM session 接口烟测。
+///
+/// **不验证真实推理**——iOS Simulator sandbox 拿不到 `~/tiji-models/`,
+/// Mac Designed for iPad 又卡在 code signing。真实推理走 macOS App 的
+/// `DebugAIRunner` 手动验证(`MeView` 底部),结果记录在 W2 retro。
+///
+/// 这里只断言:
+/// 1. `LLMSession.load(folderURL:)` 是 async throws 的 static API
+/// 2. `TokenChunk` 是 Sendable 值类型,字段齐
+/// 3. `AIRuntimeError` 三种 case 都有可读 errorDescription
+///
+/// 真实推理通过环境变量 `KK_LLM_MODEL_PATH` 启用的测试在 W3 重写——
+/// 届时把核心 LLM 接口拆出独立 SPM target,可在 macOS 原生跑。
