Split demo seed into Styles + Practice; add shuffle/samba/nañigo

Browse source 
Two seed set lists instead of one mixed "Demos":
- 🥁 Styles — grooves/feels: four-on-the-floor, swing ride, Purdie
  half-time shuffle (triplet grid, backbeat on 3, snare ghosts), Samba
  (2/4, surdo on 2), Nañigo (6/8 bembé bell), 6/8, 7/8, 5/4.
- 🎯 Practice — polyrhythms, triplet hats, accent demo, tempo builder,
  gap trainer.

Seed is now versioned + additive: a bumped SEED_VERSION adds any seed
list whose title isn't already present, without clobbering or re-adding
the user's lists.
