fix(botops): v1.2 - 彻底修复思考区域与正式回答顺序问题

问题根因：之前预创建空 AI widget，思考 widget 挂载在其后，即使动态重排也可能因 Textual 组件树更新时序导致顺序不稳定。

修复方案：
- 移除 prefab 空 AI widget 预创建逻辑
- start_ai() 仅标记状态，不创建任何 widget
- _ensure_ai_widget() 延迟到第一次 chunk 到来时才创建 AI widget
- 按消息到达顺序自然挂载：reasoning_start → reasoning → chunk → end_reasoning/finish_ai
- 思考 widget 必然先于 AI widget 挂载，顺序天然正确

同时：
- 简化 app.py 发送失败处理，不再需要移除空 widget
- 更新 README v1.2 说明

 ## 更新日志
 
+### v1.2
+- ✅ **彻底修复思考区域顺序问题**：移除预创建空 AI widget 的逻辑，改为第一次收到 `chunk` 时才创建 widget。按消息到达顺序自然挂载（`reasoning_start`→`reasoning`→`chunk`），从根本上保证思考区域始终在正式回答之前
+- ✅ 简化 `complete` 处理逻辑：仅作为收尾重置状态信号，不再进行补建逻辑
+
 ### v1.1
 - ✅ 支持 DeepSeek 思考模式展示：新增 `reasoning_start`/`reasoning`/`reasoning_end` 消息处理，思考内容以灰色斜体区域展示
-- ✅ **修复思考区域顺序问题**：通过 widget 动态重排，保证思考过程始终显示在 AI 正式回答之前（而非之后）
 - ✅ 超长思考内容自动折叠（显示最后 3000 字符）
 - ✅ 过滤"Conversation started"/"对话开始"等隐式系统通知，避免在回答末尾显示无用信息
-- ✅ 即使服务端未显式启用思考模式，若模型返回 reasoning_content 也能自动展示思考过程
 
 ### v1.0
 - 初始版本：Markdown 增量流式渲染、任务独立侧栏、自动重连、快捷键支持

+# libhttp - UniServe HTTP/WebSocket Library
+
+C++20 network library for the UniServe microservice framework, providing unified HTTP/HTTPS server and HTTP/WebSocket client capabilities built on Boost.Beast and libcurl.
+
+## Features
+
+### HttpServer
+- **HTTP/HTTPS Server**: Asynchronous HTTP 1.1 server with TLS support
+- **WebSocket Integration**: Single port can serve both HTTP(S) and WebSocket(S) endpoints
+- **Routing**: Exact path matching + wildcard (`*`) routing
+- **Middleware**: `use()` for middleware chains (CORS, auth, logging, etc.)
+- **Static Files**: `setStaticDirectory()` for serving static files
+- **Thread Pool**: Multi-threaded I/O with `asio::strand` for thread safety
+- **Client Management**: WebSocket client tracking, broadcast, and targeted send
+
+### HttpClient
+- **HTTP Client**: Synchronous HTTP requests via libcurl (GET/POST/PUT/DELETE/PATCH/HEAD/OPTIONS)
+- **WebSocket Client**: Synchronous WebSocket client via Boost.Beast
+- **Dual Protocol**: Same client instance handles both HTTP and WebSocket
+- **ws:// and wss://**: Supports both plain and TLS-encrypted WebSocket connections
+- **Binary Support**: Text and binary message sending
+- **Backward Compatible**: Original API preserved; `WebSocketClient`/`WebSocketClientBase` are aliases for `HttpClient`
+
+## Dependencies
+
+- C++20 compiler
+- Boost.Beast / Boost.Asio (header-only)
+- OpenSSL (for TLS)
+- libcurl (for HTTP client)
+- pthread
+
+## Build
+
+```bash
+make           # builds build/libus_http.so
+make install   # installs to /usr/lib and /usr/include/us (requires root)
+```
+
+Makefile links: `-lssl -lcrypto -lcurl -lpthread` with Homebrew paths for macOS.

+## Quick Start
+
+### HTTP + WebSocket Server
+
+```cpp
+#include <us/HttpServer.hpp>

+
+```cpp
+using HttpRequestHandler = std::function<http::response<http::string_body>(
+    const http::request<http::string_body>&,
+    const std::unordered_map<std::string, std::string>&)>;
+
+using MiddlewareHandler = std::function<bool(
+    const http::request<http::string_body>&,
+    http::response<http::string_body>&,
+    const std::unordered_map<std::string, std::string>&)>;
+
+using WebSocketMessageHandler = std::function<void(
+    const std::string& clientId,
+    const std::string& message,
+    std::function<void(const std::string&)> sendCallback)>;
+
+using WebSocketConnectHandler = std::function<void(
+    const std::string& clientId,
+    const std::string& remoteAddress)>;
+
+using WebSocketDisconnectHandler = std::function<void(
+    const std::string& clientId)>;
+```
+
+## Backward Compatibility
+
+The following type aliases are provided for existing code that used the standalone WebSocket client:
+
+```cpp
+using WebSocketClient = HttpClient;
+using WebSocketClientBase = HttpClient;
+```
+
+## Version History
+
+- **v3.0.0**: Merged WebSocketServer into HttpServer and WebSocketClient into HttpClient. Single-port HTTP+WebSocket support.
+- **v2.x**: Separate HttpServer, WebSocketServer, and HttpClient modules.
