"""
Regenerate resources/semantic/hgnc_cache.tsv from the CollecTRI network.

The cache is the universe of TF labels that can appear in CollecTRI-based TF
enrichment output. It is consumed by src/semantic/gene_symbols.py to classify
regulator labels as genuine gene symbols (vs unresolved). Complex/family labels
(AP1, NFKB) are intentionally excluded — they are handled earlier in
classify_regulator_label() via resources/semantic/regulator_overrides.yaml.

Run from the repo root:  python scripts/generate_hgnc_cache.py
Requires decoupler and a network connection (fetches CollecTRI from OmniPath).
