Groove Utilities Check

Checks whether you're running the latest version of groove by hitting the GitHub releases API and comparing it against what's in your local skills directory. Runs a bash script first if available for speed, otherwise falls back to standard steps. The smart bit is it caches the last check date so you're not hammering GitHub every time, and it fails silently if the network is down rather than blocking your workflow. When you're behind, it tells you exactly what command to run to upgrade. It's basic housekeeping automation, the kind of thing you'd forget to do manually until something breaks.
