2026-09-25: Dynamic shared memory of the 128x128 MMQ tile on the MMA path, as the vendored mmq_get_nbytes_shared computes it with MMQ_TILE_NE_K = 32: ids 512 B + tile_x (128 rows x tile_x_k ints) + tile_y (128 x 144 B). MMQ_MMA_TILE_X_K_Q2_K = 232 + 32 + 4 = 100; MMQ_MMA_TILE_X_K_Q3_K = 232 + 16 + 4 = 84.
