Legion Go Gyro DSU Decky Plugin v0.2.9

Correct live preview tilt direction

• Fix the 3D device preview tilting left when the physical device is tilted.
• Correct the visual roll-axis direction without changing DSU decoding or server motion data.
• Keep the Eden-aligned pitch, yaw, accelerometer, and quaternion processing introduced in v0.2.8.

This update affects only the Decky live orientation visualization.
