What does this PR do?
Adds an optional
decoder_block_out_channelsparameter toAutoencoderKLFlux2so the decoder can use different channel widths than the encoder. This is needed to support the FLUX.2 small decoder VAE (black-forest-labs/FLUX.2-small-decoder). When not set, falls back toblock_out_channels(no behavior change).Who can review?
