evaldrift: Paraphrase-Drift Scoring for LLM Eval Sets

Paraphrase-heavy eval sets drift over time: answers get rewritten, questions get reworded, and nobody re-runs the comparison that justified keeping both versions. eval_drift() scores two texts with three plain similarity measures (word-shingle Jaccard, character-trigram Jaccard, normalized Levenshtein similarity) and one blended drift score. No model calls, no network access, pure base R. Companion to the eval-methodology writing on PastAGI <https://pastagi.com>.
