chore(async-infra): 异步基础层 + 工具链 + 清理
异步基础层(core/):
- db.py aiosqlite + WAL:读路径无锁并发、写路径 asyncio.Lock 串行,
busy_timeout 自旋——实现「读写同时进行」(旧实现用 RLock 全读串行)
- http_client.py aiohttp 连接池 + 有界重试(5xx 重试 / 4xx 不重试)+
响应体上限 + 流式接口;按事件循环隔离 session(支持迁移期双 loop)
工具链:
- pyproject.toml ruff(E/F/W/I/B/UP/C4/ASYNC/S/RUF) + pyright(basic) + pytest(asyncio auto)
- requirements-fastapi.txt FastAPI/aiohttp/aiosqlite/aiofiles 等目标栈
- requirements-dev.txt 开发依赖(pytest/ruff/pyright)
清理:删除无用脚本 _csscheck.py 与产物标记 _css_ok.txt/_pkg_ok.txt,同步 .gitignore
验证:pytest 10/10(含「写 200 条同时 4 读协程零异常」并发用例);
ruff All checks passed;pyright 0 errors。
