/**
 * Computes a blended specificity score for every card:
 *  - Global specificity: cosine distance from the full-corpus centroid (0.4 weight)
 *  - Per-repo specificity: cosine distance from each card's own repo centroid (0.6 weight)
 *
 * Cards that are generic within their own repo (like hub models) get penalized
 * even if they look "unique" from the global perspective.
 *
 * Also invalidates the query-classifier centroid cache since embeddings changed.
