重构: 插件自注册 + .so 动态加载 + 中断打断机制

- 所有内置插件 init() 自注册 (plugin.RegisterFactory), 移除 main.go 硬编码
- 新增 .so 动态加载器 (internal/plugin/dynamic.go), 插件可编译为 plugin.so
- 新增 plugin.json 元数据 (internal/plugin/manifest.go)
- 新增 interceptLoop 独立 goroutine:
  (a) cancelLLM() 取消进行中的 HTTP 请求
  (b) interceptCh → drainInterrupt() 注入 [打断消息] 到 LLM 上下文
  (c) InjectInput 空闲时触发新处理循环
- 新增 internal/plugins/all.go 空白导入触发所有内置插件 init()
- internal/sdk/ 作为 PluginSDK 正式 Go API
- internal/api/ → internal/plugins/webui/ 迁移
- 删除旧 cmd/cli/, 使用 cmd/waiter/ 替代
- 更新 PLAN.md / ARCHITECTURE.md / README.md 文档
