/**
 * P1: URL Pattern LLM Completion
 *
 * After BFS crawl completes, runs a single LLM call to predict URLs that exist
 * but were never linked from within the app. Validates each candidate with
 * HTTP HEAD before emitting as crawl evidence (URL_CANDIDATES).
 *
 * Cost: ~1 LLM call + N HEAD requests. Takes ~5-30 seconds depending on
 * candidate count. Does NOT launch a browser.
