refactor: Web 服务内嵌主进程 + 文档移到 docs/ 二级目录

1. Web 服务改为 threading 模式：
   - 新增 run_web_server(port) / stop_web_server() 函数
   - TUI 通过 from web_api import run_web_server 直接调用
   - 使用 werkzeug make_server 实现线程内优雅启动/停止
2. 构建脚本精简为单二进制：
   - 移除 trulymem-web 独立打包步骤
   - 添加 werkzeug 到 hidden-imports
3. 详细启动文档移到 docs/zh/quick_start.md
4. README 精简为概述，指向 docs/ 目录
