/**
 * CLI helper for validate-news-generation.sh Check 15.
 *
 * Sources banned patterns from the canonical BANNED_PATTERNS list in shared.ts
 * so the bash script does not maintain a duplicate pattern set.
 * Also detects unresolved AI_MUST_REPLACE markers in HTML comments.
 *
 * Usage: npx tsx scripts/check-banned-patterns.ts news/*.html
 * Exit code: number of articles containing banned patterns (0 = clean)
 * Stdout: one JSON line per offending file: {"file":"…","labels":["…"]}
