L4 的归属此前写成“只有内核(panic/selfip)”,这是不完整的:**内核级插件**
(编译期内置插件,如 webui/cli/timer)也需要它来实现中断能力——最典型的例子
就是 WebUI 的终止按钮:用户按下时必须有一条能立刻打断当前任务的中断。
- 新增 `PriorityL4 = "L4"`,注释写明“仅内核级(内置)插件可用”。
- `InjectOptions.Priority` 的注释同步更正:取值 L1..L4,L4 属内核级插件,
外部插件声明 L4 会被内核夹到 L3。
为什么不能给外部插件:否则任何第三方插件都能随时打断用户的一切工作。
夹取有**两道闸**(纵深防御):
1. proc 桥(外部进程唯一入口)一律把 L4 夹到 L3——在这里夹是因为
`source` 是插件自报字段、可以冒名;
2. 内核侧再按 `IsBuiltinPlugin(source)` 判一次。
`source` 约定为 `插件名` 或 `插件名/实例`(webui/<deviceID>),判据取第一段。
兼容性:纯追加,零值仍等价于 L1。
