Krea2 Adaptive Progressive Sampler

Experimental seed-preserving progressive Euler sampler for Krea2. It denoises at half or quarter latent resolution, then restores the original seed's orthogonal high-frequency noise at the correct flow sigma. Use with SamplerCustomAdvanced and a simple/Flux sigma schedule.
