Previously, identify_missing_models grouped missing entries only by filename,
which could merge unrelated models from different categories that happen to
share a filename. This change deduplicates by (category, filename) and tracks
all_node_refs with a reference_count so the frontend can preserve one
resolution per node reference instead of collapsing duplicates.
Frontend changes in resolve_download_methods.js iterate over all_node_refs,
and missing_browser_methods.js now shows '+ N refs' in the missing-model
label and clarifies the locate tooltip when multiple workflow references
share the same missing model.
