Feature: Add MCP (Model Context Protocol) server integration

Add an optional MCP server (JSON-RPC 2.0 over Streamable HTTP) exposing an online-host listing tool, protected by a Bearer token. Disabled by default; configured via a new "Extensions > MCP Settings" dialog. - McpServer: httplib + JSON-RPC 2.0 dispatch (initialize/ping/tools/list/tools/call) - McpSettingsDlg: runtime-created dialog for enable/port/bind/token - HostJson: extract single-host JSON serialization shared with WebService - FRP: expose MCP port (union with listening/Web ports) when bound to 0.0.0.0 - i18n: en_US / zh_TW translations Co-Authored-By: deepseek-v4-pro
