GWAS Trait-to-Gene Discovery Implementation

This module provides a high-level function to discover genes associated with
diseases/traits using GWAS data from GWAS Catalog and Open Targets Genetics.

Example:
    >>> from tooluniverse_skills import discover_gwas_genes
    >>> results = discover_gwas_genes("type 2 diabetes")
    >>> for gene in results[:5]:
    ...     print(f"{gene.symbol}: p={gene.min_p_value:.2e}, evidence={gene.evidence_count}")
