W17: extract ai_common shared module + fix anthropic data race + brace bugs

- New plugins_upper/ai_common/ static library: shared PluginConfig, ToolCallAccum,
  StreamContext, secure_zero, extract_host_port, serialize_tool_calls, free_chat_result
- Refactored openai/anthropic plugins to use dstalk_ai:: namespace from ai_common
- Fixed anthropic g_config raw pointer → std::atomic (data race)
- Added SSE parse error counter with threshold abort (kMaxSseParseErrors=5)
- Fixed missing closing brace in both plugins' error-body catch block
- Updated test targets: ai_common include path + link, using namespace dstalk_ai
- plugin_loader_test: added stub_unreg + service_registry.cpp for unregister_service
- Includes pre-existing uncommitted changes from prior waves

每种服务都有一个预定义的 vtable 结构体(定义在 `dstalk_services.h`)。第三方也可以扩展自己的服务 vtable版本号随注册一起提供允许消费者做最低版本检查。
服务注册采用 **name + version** 两要素:
- 全局唯一名称(如 `"ai.openai"``"http"``"file_io"`)。
- 全局唯一名称(如 `"ai_openai"``"http"``"file_io"`)。
- 版本号(消费者可以要求 `min_version`)。

**契约 3register_service 注册自己的服务。** 插件将自己的 vtable 注册到服务注册表后,其他依赖它的插件才能在后续的 `on_init` 中通过 `query_service` 找到它。
```c
return host->register_service("ai.openai", 1, &g_service);
return host->register_service("ai_openai", 1, &g_service);
```
注册表内的 vtable 是原始指针,不拷贝。因此 vtable 指向的结构体必须是**静态生命周期**(全局变量或 static 局部变量)。
