Flux output norm projection chain

32 eligible runs
rmsnorm

Flux's final output processing chain combining AdaLayerNormContinuous normalization with output projection. Performs: (1) LayerNorm without affine parameters, (2) SiLU activation on temb followed by linear projection to extract shift/scale modulation parameters, (3) element-wise modulation (shift and scale), (4) large linear projection to output space.
