Add LumaFlux and ComfyUI-CachedSearch

[shreshthsaini]

Registers two node packs.

LumaFlux (https://github.com/shreshthsaini/LumaFlux): SDR-to-HDR conversion with LumaFlux (arXiv 2604.02787). The paper repository doubles as the node pack (root __init__.py registers the nodes in comfyui/). A loader for the frozen FLUX.1-dev backbone (diffusers repo or the single-file checkpoints already in models/diffusion_models and models/vae) plus the released 71M-parameter adapters, a converter that runs the reference pipeline with video stabilization across a batch, an SDR preview, and save nodes for 16-bit PQ PNG (cICP-tagged) and 10-bit HEVC PQ video. requirements.txt holds the inference-only dependencies; the nodes import the package from src/.

ComfyUI-CachedSearch (https://github.com/shreshthsaini/ComfyUI-CachedSearch): best-of-N seed search (CachedSearch, arXiv 2607.23159). The drafts run under the native EasyCache node, an ImageReward verifier scores them, and only the winning seed is re-sampled at full compute. Sampler and verifier nodes; requirements.txt adds image-reward.

Both load cleanly with Use local DB checked. I maintain both repositories and am an author of both papers.
