Legion Go Gyro DSU Decky Plugin v0.2.6

Legion Go Gyro DSU Decky Plugin v0.2.6

This release corrects the gyro axis reconstruction used by the live device
orientation view.

Fixed

• Corrected the mapping of DSU gyro fields pitch, yaw, and roll.
• Updated the orientation filter to use the gyro axes in the expected
  roll/pitch/yaw order.
• Fixed incorrect or swapped movement in the live 3D device visualization.
• Updated the DSU decoder tests to cover the corrected axis mapping.

Included fixes from previous versions

• Package Python backend modules in Decky's supported py_modules directory.
• Request root access using Decky Loader's supported root manifest flag.
• Prevent systemd status requests from blocking Decky's event loop.
• Prevent SteamOS system tools from loading Decky's bundled OpenSSL libraries.
• Display actual backend errors instead of incorrectly reporting that
  lgsdsu.service is not installed.
