New way switch_midway (refine, want midway): the canvas's sampler becomes
two KSampler Advanced parts, the first on the canvas's model up to step
21, the second on a new loader from there, taking the old sampler's place
and links. On Anima it takes the tested sampling (35 steps,
dpmpp_2m_sde_gpu, beta): er_sde comes out grainy when split, even with
the same model in both parts, which the AI is told.
refine_other_model and upscale_two_models get Anima variants: a UNET
loader "like" the canvas's, reusing its text encoder, VAE and prompts; on
Anima the second-model upscale is the Tile route the user verified (1.22x
latent, LLLite 0.7, denoise 0.85, ColorMatch).
A node "like" or replacing a sampler now takes its seed as noise_seed on
KSampler Advanced and the other way round. The scene argument's
description is shorter to keep the tool list within its budget.
Ran on the isolated test ComfyUI on an Anima canvas: each way built
through add_nodes and made a picture (79 s, 148 s, 127 s on 6 GB).
