Summary

• Remove the legacy native MotionEvent/libinput input-hook paths; Java Activity forwarding is the only input path for ImGui and Android mods.
• Keep the Java input bridge and mod-facing touch, keyboard, and timestamp APIs.
• Requires a host APK that exposes the Java Activity input-forwarding bridge.

Validation

• GitHub Actions run #36322905812 passed: Android DLL, Android AAR, and Windows jobs.
• No on-device runtime verification has been performed.

Known limitation

• If Java bridge registration fails, InstallInputHooks() logs the failure but still sets IsInitialized = true; the pending diagnostic-state correction is not included in this branch.
