Expand description

2026-09-28: The projection launcher: the W4A4 FP4 MMA when the tier admits the weight (weight_rows), the kernels are prepared and w4a4_route admits the shape, else the W4A16 w4a16_gemv_batchm (which tries the tensor-core GEMV first). The W4A16 fallback returns an error above W4A4_MAX_M rows.
