阶段1：服务化骨架（FastAPI + Playwright worker + 任务队列）
- 新增 runtime.py：抽离共享核心 launch_and_prepare / dispatch_task / run_heartbeat /
probe_* / launch_anneng / RuntimeContext，常量 SITES_CONFIG 等；main_router 复用
- 新增 server.py：FastAPI（主线程）+ Playwright worker（独立线程）+ 任务队列；
API：POST/GET /tasks、GET /status、GET /data/{file}（防路径穿越）
- state_store：加 task_history 表 + create/update/get/list 接口
- 5 站点 with_retry 改为返回 True/False，供 dispatch_task 判成败
- main_router：重写为复用 runtime 的交互模式（行为不变）
- requirements：加 fastapi、uvicorn
- CLAUDE.md：补充运行模式与共享核心架构说明
线程模型：主线程 FastAPI 不碰 Playwright，worker 线程独占 page，经 Queue + SQLite 通信。

# 阶段1：服务化共享核心。把"启动浏览器 + 各站就绪 + 弹窗 + 心跳初值"

# 共同复用，避免两处重复维护。

# 线程模型：launch_and_prepare 内 sync_playwright().start() 必须在"持有 Playwright 的

# 线程"调用（交互模式=主线程；服务模式=worker 线程）。该线程独占所有 page 操作；
|

# 其他线程（如 FastAPI 路由）只能经 task_queue + state_store 与之通信，绝不跨线程
