Restore the old HyperOS two-finger small-window gesture on HyperOS 4 (Xiaomi 17 Pro Max, Android 17).

On older HyperOS/MIUI versions, while an app is foreground you could:

1. Swipe up from the bottom edge with your thumb and keep holding (enters recents drag).
2. Press anywhere with your index finger (nothing visible happens yet).
3. Release your thumb — the window is dragged to the index-finger position.
4. Release your index finger — the window drops into small-window mode there.

On HyperOS 4 the second finger cancels the drag instead. This LSPosed module restores the old behavior by installing an android.view.InputFilter inside system_server.

• Android 16+ (targetSdk 36+)
• LSPosed (libxposed API 102+)
• Root (Magisk / APatch / KernelSU)

1. Install the APK from the latest Release.
2. Enable the module in LSPosed, scope: system (and com.android.systemui).
3. Reboot.

• Only injects into system_server and com.android.systemui.
• Debug log: adb logcat -s SmallWindowInputFilter:I
• Diagnostics build: every release also carries io.github.zilewang7.smallwindow-*_debug_diag.apk; it writes gesture decisions to /data/system/smallwindow_filter.log (root-readable) for issue reports

恢复 HyperOS 4（小米 17 Pro Max，Android 17）上的旧版双指挂小窗手势。

旧版系统上：拇指从底部上滑进入多任务并按住 → 食指按住任意位置 → 松开拇指，窗口被拖到食指位置 → 松开食指，挂成小窗。HyperOS 4 上第二指会取消拖拽，本模块通过在 system_server 中安装 InputFilter 恢复旧行为。

• 需要：Android 16+、LSPosed（libxposed API 102+）、Root
• 安装：安装最新 Release 的 APK → LSPosed 中启用并勾选 system 作用域 → 重启
• 日志：adb logcat -s SmallWindowInputFilter:I
• 诊断版：每个 Release 附带 io.github.zilewang7.smallwindow-*_debug_diag.apk，手势决策写入 /data/system/smallwindow_filter.log（root 可读），反馈问题请附上该日志
