release: v5.4.1

- 新增 xcli_core/tool_result.py: ToolResult + ErrorCode
- unified_tool_manager: execute/mcp_call 返回 ToolResult
- cmd_executor: 所有返回改为 ToolResult
- file_manager: 所有返回改为 ToolResult
- 兼容旧接口: execute_dict() 返回 dict, handler 可返回 str 或 ToolResult

+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:
