Mobile client 1.3: better joypad controls

MU ALAMAT's Android client has been updated for open beta testing. The joypad now follows its own finger, so movement and skill buttons can track separate touches. Steering follows the camera, uses a smaller neutral zone and keeps direction changes steady. Short movement routes refresh while walking, with wall sliding where one direction remains clear. Releasing or recentering the joypad stops movement. The classic HUD, equipment glow and rule that skills pause movement are retained. The Android download uses the ARM64 Release build with AOT and LLVM enabled. Install the update over the existing app to keep downloaded game data. Please report control issues with your device model. Performance and control comfort still need testing on individual phones. Find the current Android build on the Downloads page. The PC download will be added after its client package is uploaded.
