fix(runtime): 修复 Skill/MCP 调用链路3个断点

1. Anthropic Driver ToolResult 格式修复 — ContentBlock 添加 ToolResult 变体,
   tool_call_id 不再被丢弃, 按 Anthropic API 规范发送 tool_result 格式
2. 前端 callMcpTool 参数名对齐 — serviceName/toolName/args 改为
   service_name/tool_name/arguments, 后端支持 service_name 精确路由
3. MCP 工具桥接到 ToolRegistry — McpToolAdapter 添加 service_name/clone,
   新建 McpToolWrapper 实现 Tool trait, Kernel 添加 mcp_adapters 共享状态,
   McpManagerState 与 Kernel 共享同一 Arc<RwLock<Vec>>, MCP 服务启停时
   自动同步工具列表到 LLM 可见的 ToolRegistry
