feat(runtime): add new internal architecture with protocol clients

Implement the new _internal package structure for AstrBot runtime:
- Add AstrbotOrchestrator with LSP, MCP, ACP, ABP protocol clients
- Add AstrbotGateway server with WebSocket support
- Add comprehensive test suite for runtime module
- Add tools base module for MCP tools

Implements bootstrap function using anyio task groups for
concurrent protocol client initialization.

+   └────┬────┘
+        │ start()
+        ▼

+   │ SHUTDOWN │─── all clients closed, ready for GC
+   └──────────┘
+
+ Transitions:
+   INIT + start() ──► RUNNING
+   RUNNING + shutdown() ──► SHUTDOWN
+
+ For each protocol client, the orchestrator:
+   1. Creates instance in __init__
+   2. Calls connect() to initialize
+   3. Calls protocol-specific setup (connect_to_server, etc)
+   4. Manages via run_loop() heartbeat
+   5. Calls shutdown() on final cleanup
+
+
+Star Registration Flow

+
+
+run_loop() Responsibilities
+===========================
+
+   while running:
+       │─ check LSP server health (ping/heartbeat)
+       │─ check MCP session status (reconnect if needed)
+       │─ check ACP client connections
+       │─ process any pending star notifications
+       │─ sleep(SLEEP_INTERVAL)
+
+
+Shutdown Sequence
+==================
+
+   shutdown()
+       │
+       ├─ set _running = False
+       │
+       ├─ LSP.shutdown()

+       │     └─ terminate subprocess
+       │
+       ├─ ACP.shutdown()

+       └─ MCP.cleanup()
+             └─ close all sessions
+             └─ cleanup subprocesses
+
+
+Exception Handling
+==================
+
+   Each protocol client should:
+   - Catch connection errors
+   - Attempt reconnection with exponential backoff
+   - Log errors but don't crash run_loop
+   - Raise on irrecoverable failures
+
+   The orchestrator run_loop should:
+   - Catch CancelledError on shutdown
+   - Catch Exception and log (don't crash)
+   - Ensure cleanup runs in finally block

+# 开发者日记@lightjunction
+为了避免和主分支发生大量冲突，新架构设计全部移动至了_internel包
+目前API不稳定，并不希望外部导入这个内部包
+新增astrbot dev子命令用于启动新架构
+概念：
+核心运行时：core runtime 
+核心运行时是主进程
+主要是启动一个后端，这个后端将改为使用fastapi开发
+插件称呼为star
+astrboot，这个名字就和星系相关，插件当然就是一个一个星星了
+Galaxy是星系
+我们的核心运行时需要一个协议和插件对话
+我思考，我们的插件，最好是可以做到和lsp服务器或者mcp服务器那样
+我们需要一套新的协议
+我列举本项目采用的协议如下：
+lsp协议：client
+mcp协议：client + server
+acp协议：client + server 
+abp协议：astrbot protocol client + server (相当于内置插件)
+协议层只管传输
+runtime则负责响应和调度
+异步库使用anyio
+## 类型标注
+需要通过ty类型检查
+避免使用Any cast
+## 代码风格
+需要通过ruff检查
+## 细节
+使用uv run 运行一切，别用python xxxx
