feat: 添加带有消息处理和路由功能的NEW_napcat_adapter插件

- 为NEW_napcat_adapter插件实现了核心模块，包括消息处理、事件处理和路由。
- 创建了MessageHandler、MetaEventHandler和NoticeHandler来处理收到的消息和事件。
- 开发了SendHandler，用于向Napcat发送回消息。
引入了StreamRouter来管理多个聊天流，确保消息的顺序和高效处理。
- 增加了对各种消息类型和格式的支持，包括文本、图像和通知。
- 建立了一个用于监控和调试的日志系统。

+
+基于 mofox-bus v2.x 的 Napcat 适配器（使用 BaseAdapter 架构）
+
+## 🏗️ 架构设计
+
+本插件采用 **BaseAdapter 继承模式** 重写，完全抛弃旧版 maim_message 库，改用 mofox-bus 的 TypedDict 数据结构。
+
+### 核心组件
+- **NapcatAdapter**: 继承自 `mofox_bus.AdapterBase`，负责 OneBot 11 协议与 MessageEnvelope 的双向转换
+- **WebSocketAdapterOptions**: 自动管理 WebSocket 连接，提供 incoming_parser 和 outgoing_encoder
+- **CoreMessageSink**: 通过 `InProcessCoreSink` 将消息递送到核心系统
+- **Handlers**: 独立的消息处理器，分为 to_core（接收）和 to_napcat（发送）两个方向
+

+
+## 🚀 快速开始
+
+### 使用方式
+
+1. **配置文件**: 在 `config/plugins/NEW_napcat_adapter.toml` 中配置 WebSocket URL 和其他参数
+2. **启动插件**: 插件自动在系统启动时加载
+3. **WebSocket连接**: 自动连接到 Napcat OneBot 11 服务器
+
+## 🔑 核心数据结构
+
+### MessageEnvelope (mofox-bus v2.x)
+
+```python
+from mofox_bus import MessageEnvelope, SegPayload, MessageInfoPayload
+
+# 创建消息信封
+envelope: MessageEnvelope = {
+    "direction": "input",
+    "message_info": {
+        "message_type": "group",
+        "message_id": "12345",
+        "self_id": "bot_qq",
+        "user_info": {
+            "user_id": "sender_qq",
+            "user_name": "发送者",
+            "user_displayname": "昵称"
+        },
+        "group_info": {
+            "group_id": "group_id",

+    },
+    "message_segment": {
+        "type": "seglist",
+        "data": [
+            {"type": "text", "data": "hello"},
+            {"type": "image", "data": "base64_data"}
+        ]
+    },
+    "raw_message": "hello[图片]",
+    "platform": "napcat",
+    "message_id": "12345",
+    "timestamp_ms": 1234567890
+}
+```
+
+### BaseAdapter 核心方法
+
+```python
+class NapcatAdapter(BaseAdapter):
+    async def from_platform_message(self, message: dict[str, Any]) -> MessageEnvelope | None:
+        """将 OneBot 11 事件转换为 MessageEnvelope"""
+        # 路由到对应的 Handler
+        
+    async def _send_platform_message(self, envelope: MessageEnvelope) -> dict[str, Any]:

+
+## 🔍 关键实现细节
+
+### 1. MessageEnvelope vs 旧版 MessageBase
+
+**不再使用 Seg dataclass**，全部使用 TypedDict：
+
+```python
+# ❌ 旧版（maim_message）
+from mofox_bus import Seg, MessageBase
+
+seg = Seg(type="text", data="hello")
+message = MessageBase(message_info=info, message_segment=seg)
+
+# ✅ 新版（mofox-bus v2.x）
+from mofox_bus import SegPayload, MessageEnvelope
+
+seg_payload: SegPayload = {"type": "text", "data": "hello"}
+envelope: MessageEnvelope = {
+    "direction": "input",
+    "message_info": {...},
+    "message_segment": seg_payload,
+    ...
+}
+```
+
+### 2. Handler 架构模式
+
+**接收方向** (to_core):
+```python
+class MessageHandler:
+    def __init__(self, adapter: "NapcatAdapter"):
+        self.adapter = adapter
+    
+    async def handle_raw_message(self, data: dict[str, Any]) -> MessageEnvelope:
+        # 1. 解析 OneBot 11 数据
+        # 2. 构建 message_info（MessageInfoPayload）
+        # 3. 转换消息段为 SegPayload
+        # 4. 返回完整的 MessageEnvelope
+```
+
+**发送方向** (to_napcat):
+```python
+class SendHandler:
+    def __init__(self, adapter: "NapcatAdapter"):
+        self.adapter = adapter
+    
+    async def handle_message(self, envelope: MessageEnvelope) -> dict[str, Any]:
+        # 1. 从 envelope 提取 message_segment
+        # 2. 递归转换 SegPayload → OneBot 格式
+        # 3. 调用 adapter.send_napcat_api() 发送
+```
+
+### 3. API 调用模式（响应池）
+
+```python
+# 在 NapcatAdapter 中
+async def send_napcat_api(self, action: str, params: dict[str, Any]) -> dict[str, Any]:
+    # 1. 生成唯一 echo
+    echo = f"{action}_{uuid.uuid4()}"
+    
+    # 2. 创建 Future 等待响应
+    future = asyncio.Future()
+    self._response_pool[echo] = future
+    
+    # 3. 发送请求（通过 WebSocket）
+    await self._send_request({"action": action, "params": params, "echo": echo})
+    
+    # 4. 等待响应（带超时）
+    try:
+        result = await asyncio.wait_for(future, timeout=10.0)
+        return result
+    finally:
+        self._response_pool.pop(echo, None)
+
+# 响应回来时（在 incoming_parser 中）
+def _handle_api_response(data: dict[str, Any]):
+    echo = data.get("echo")
+    if echo in adapter._response_pool:
+        adapter._response_pool[echo].set_result(data)
+```
+
+### 4. 类型提示技巧
+
+处理 TypedDict 的严格类型检查：
+
+```python
+# 使用 type: ignore 标注（编译时是 TypedDict，运行时是 dict）
+envelope: MessageEnvelope = {
+    "direction": "input",
+    ...
+}  # type: ignore[typeddict-item]
+
+# 或在函数签名中使用 dict[str, Any]
+async def from_platform_message(self, message: dict[str, Any]) -> MessageEnvelope | None:
+    ...
+    return envelope  # type: ignore[return-value]
+```
+

+## 📚 参考资料
+
+- **mofox-bus 文档**: 查看 `mofox_bus/types.py` 了解 TypedDict 定义
+- **BaseAdapter 示例**: 参考 `docs/mofox_bus_demo_adapter.py`
+- **旧版实现**: `src/plugins/built_in/napcat_adapter_plugin/` (仅参考逻辑)
+- **OneBot 11 协议**: [OneBot 11 标准](https://github.com/botuniverse/onebot-11)
+
+## ⚠️ 重要注意事项
+
+1. **完全抛弃旧版数据结构**
+   - ❌ 不再使用 `Seg` dataclass
+   - ❌ 不再使用 `MessageBase` 类
+   - ✅ 全部使用 `SegPayload`（TypedDict）
+   - ✅ 全部使用 `MessageEnvelope`（TypedDict）
+
+2. **BaseAdapter 生命周期**
+   - `__init__()` 中初始化同步资源
+   - `start()` 中执行异步初始化（WebSocket连接自动建立）
+   - `stop()` 中清理资源（WebSocket自动断开）
+
+3. **WebSocketAdapterOptions 自动管理**
+   - 无需手动管理 WebSocket 连接
+   - incoming_parser 自动解析接收数据
+   - outgoing_encoder 自动编码发送数据
+   - 重连机制由基类处理
+
+4. **CoreSink 依赖注入**
+   - 必须在插件加载后调用 `set_core_sink(sink)`
+   - 通过 `get_core_sink()` 全局访问
+   - 用于将消息递送到核心系统
+
+5. **类型安全与灵活性平衡**
+   - TypedDict 在编译时提供类型检查
+   - 运行时仍是普通 dict，可灵活操作
+   - 必要时使用 `type: ignore` 抑制误报
+
+6. **参考旧版但不照搬**
+   - 旧版逻辑流程可参考
+   - 数据结构需完全重写
+   - API调用模式已改变（响应池）
+
+## 📊 预估工作量
+
+- ✅ 核心架构: **已完成** (BaseAdapter + Handlers 骨架)
+- ⏳ 消息处理完善: **4-6 小时** (所有消息类型 + 工具函数)
+- ⏳ 发送处理完善: **3-4 小时** (所有 Seg 类型 + 命令)
+- ⏳ 通知事件处理: **2-3 小时** (poke/emoji_like/recall/ban)
+- ⏳ 测试调试: **2-4 小时** (全流程测试)
+- **总剩余时间: 11-17 小时**
+
+## ✅ 完成标准
+
+当以下条件全部满足时，重写完成：
+
+1. ✅ BaseAdapter 架构实现完成
+2. ⏳ 所有 OneBot 11 消息类型支持
+3. ⏳ 所有发送消息段类型支持
+4. ⏳ 所有通知事件正确处理
+5. ⏳ 权限系统集成完成
+6. ⏳ 与旧版功能完全对等
+7. ⏳ 所有测试用例通过
+
+---
+
+**最后更新**: 2025-11-23
+**架构状态**: ✅ 核心架构完成
+**实现状态**: ⏳ 消息处理部分完成，需完善细节
+**预计完成**: 根据优先级，核心功能预计 1-2 个工作日
