feat: MCP stdio server + TUI回车发送 + 子Agent无限制 + 安全引擎优化 + diff弹窗绿红背景

- 新增 mcp_server.py: 标准 MCP stdio 传输层入口
- TUI: 回车发送消息,Shift+回车换行 (SendTextArea子类)
- 子Agent: 移除 max_steps=20 限制
- 安全引擎: 移除 ALWAYS_CONFIRM 关键词强制拦截
- code_editor: diff弹窗绿底(+)/红底(-)背景色

"""
小狸 MCP Stdio Server
=====================
标准 MCP (Model Context Protocol) stdio 传输层入口。
通过 stdin/stdout 以 JSON-RPC 2.0 格式通信,
可被 Claude Desktop、Cursor、OpenClaw 等标准 MCP 客户端直接连接。
用法:
python mcp_server.py [--plugins-dir plugins] [--skills-dir skills]
Claude Desktop 配置示例:
{
"mcpServers": {
"xiaoli": {
"command": "python",
"args": ["/path/to/xiaoli-cli/mcp_server.py"]
}
}
}
