- core/workflow_analyzer.py: add dynamic widget category hint extraction via threaded cache and sentinel-prefix matching; get_model_widget_category_hints now returns all inferred categories including dynamic ones, improving model folder detection for workflows with encoded category metadata.
- web: add ? help icon with context-aware tooltip to download folder selector explaining why a category was auto-selected (preserved manual choice, node type hint, workflow-detected category, default fallback, or best available). Tooltip refreshes live as the user changes the folder selection.
- web/css/resolver-main.css: style the new category help badge.
- metadata/huggingface-author-index.json: update index entry.
