SPTestSettings.fast() was identical to detailed(), generating the full
cross-product of eager/compiled × chunked/no-chunk × pp1/pp2 × mp/ray
(8 setups × 2 backends = 16 combos, ×2 for inductor = 32 tests).
Slim it down to 2 representative setups (compiled + chunked prefill,
with pp=1 and pp=2) and a single backend (mp). Remove the unused
detailed() method entirely.
