install_ugreen_leds_controller v2.0.9

[2.0.9] - 2026-04-18

Added

Kernel Module Version Fallback (#15)

• When the pre-built led-ugreen.ko for the running TrueNAS SCALE version is
  not available on GitHub, the installer now automatically tries earlier patch
  versions within the same YY.MM release train (e.g. 25.04.1 → 25.04.0)
  before failing.
• A clear warning block is logged when a fallback version is used, showing both
  the requested version and the version actually downloaded.
• The .version file continues to store the running TrueNAS version (not
  the fallback), so skip-download logic on the next boot remains correct.

Fixed

Octal Arithmetic in Patch Version Calculation (#16)

• Patch version strings like 08 or 09 were treated as invalid octal by
  bash arithmetic expansion, causing the fallback loop to error. Fixed by using
  $(( 10#$patch )) to force decimal base.
