Expand description

W8A16 (FP8 E4M3) GEMV with fused SiLU input: silu(gate)*up as activation, GEMV with FP8 down weights. Reads gate_out[K] and up_out[K] BF16, computes silu(gate)*up per element inline, then multiplies by dequanted FP8 down weights. Eliminates the separate silu_mul kernel + down GEMV. Mirrors w4a16_gemv_silu_input but with RAW DevicePtrs (no scale2 f32).
