Legion Go 1 - Gyro not working on latest controller firmware

[tctinh]

Problem

The Legion Go 1 has three gyro sources:

• Left controller
• Center sensor in the handheld
• Right controller

InputPlumber could eventually allow users to select between these gyro sources. However, enabling multiple sources at the same time may produce duplicate or competing motion input.

For a simple and predictable initial implementation, the right-controller gyro should be used exclusively. This provides one consistent motion source that works while the controller is attached in handheld mode and while it is detached.

Expected Behavior

• Use the right-controller accelerometer and gyroscope.
• Support both handheld and detached-controller use.
• Filter the left-controller and center gyro sources to avoid competing motion streams.
• Consider configurable left, center, or right gyro selection as a future enhancement.

Implementation

PR #677 implements the right-controller approach:
