Update the README to align with the latest node capabilities, shifting the description from "granular nodes" to "exhaustive control" over all API parameters. Key changes include documenting new features like live tooltips, metadata recovery (actual_seed), and improved batch processing. The node reference was also updated to clearly distinguish between required and optional parameters and to reflect the latest supported models.
Replace the unified inference node with dedicated nodes for Flux.1/2, Qwen, and Z models to provide model-specific parameters and better UX. Refactor the API client to simplify image model detection using strict prefixes (black-forest-labs/, Qwen/, Tongyi-MAI/) and remove unused caching logic. Update __init__.py to register all new nodes and print a concise load summary.
