android_wait_for_idle

Wait for the UI to become idle by comparing accessibility tree fingerprints using similarity-based change detection. Generates a 256-slot histogram fingerprint of the tree structure and uses normalized difference to compute a similarity percentage. Considers UI idle when two consecutive snapshots (500ms apart) meet the `match_percentage` threshold.
