feat: v3.6 重构 - 拆分 ai_cli.py 为模块化架构

本次更新由 mimo 自动化执行，与开发者无关。
新增 xiaoli/ 包:
- __main__.py: 入口点 (python -m xiaoli)
- app.py: 主应用薄编排层（~400行 vs 原3860行）
- config.py: 配置管理
- engines.py: AI 引擎管理
- sandbox.py: 代码安全沙箱
- prompt.py: 系统提示词构建
- conversation/: 对话解析器 + 历史管理
- display/: CLI/TUI 双模式输出
改进:
- 支持 argparse (--tui, --engine, --version)
- 插件命令注册表
- 更新 README
- 更新 .gitignore
原 ai_cli.py 保留向后兼容
