test: commit example snapshots omitted from earlier feature commits

The race (9099735e), Phase 0 (2f2d7f1d), Phase 1 (5c30bfe0) and tuple-store
(6a976287) commits added each example's .sx but their `git add NNNN-*` glob
missed the sibling expected/ snapshots (a different directory). The suite
passed locally because snapshots are read from disk, but the commits were
incomplete — a fresh checkout would have no goldens. Add them now.
