Reduce the test matrix by trimming:
- NUM_TOKENS_HIDDEN_SIZES: 19 → 4 combos (keep small, misaligned,
medium-aligned, large-misaligned)
- GROUP_SIZES: drop [1, 64] (redundant with [1, 128])
- Inline group_size/tma_alignment combos to 3 meaningful cases
instead of full Cartesian product (7)
Covers the same code paths (per-token, per-block, TMA alignment)
with fewer redundant combinations.
