Detect LilyPond with shutil.which; hide the feature when absent.

Feasibility confirmed on LilyPond 2.26: a 4-voice ChoirStaff with lyrics renders via lilypond -dcrop=#t -dbackend=cairo --png -dresolution=600 to a tight-cropped 4317×1617 grayscale PNG with consistent 41.5px staff-line spacing.

Done: the tool runs identically on a machine without LilyPond, with no error and no dead UI.
