Add a continuous ~4:00 demo song set list

Browse source 
New "🎵 Song" seed list (SEED_VERSION 3): 8 bar-length segments that
auto-advance through tempo ramps (92→120 build, 132→83 outro), a 2/4
samba, a half-time shuffle, a 909 four-on-the-floor and a 16th peak —
totalling ~4:00. Also gate bar-count auto-advance on the Continue toggle
(matches its "countdown / bars" label; only bar-length items are
affected, which previously didn't exist outside this song).
