+# niri-force-kill-window
+# 通过鼠标点击强制结束 (SIGKILL) 任意窗口。
+# 完美支持 Wayland 原生与 XWayland 代理窗口的独立精准击杀。
+# 具备多语言自适应 (i18n) 与智能依赖提示功能。
+#
+# 实现原理：
+# 1. 通过 niri msg pick-window 点选窗口
+# 2. 利用窗口的 PID，通过进程名称判断它是 xwayland 还是 wayland
+# 3. 获取真实的底层 PID（Wayland 直接取用，XWayland 利用 xprop 获取焦点窗口的真实 PID）
+# 4. 向上追溯该真实 PID，找到所属应用的根进程 (App Root)，并利用防火墙逻辑避开系统进程
+# 5. 从根进程向下遍历收集所有子孙进程，利用 kill -9 执行“九头蛇绞杀”，防止多进程软件死灰复燃
