/**
 * Database Antipatterns Scanner
 *
 * Detects scalability and database antipatterns in JavaScript/TypeScript projects.
 * Drizzle-first detection with fallback to generic/raw-SQL patterns.
 *
 * Detections:
 *  1. Missing pagination — unbounded SELECT / findMany / db.select() with no LIMIT/take
 *  2. SELECT * / over-fetch — bare SELECT * or Drizzle select with no column projection
 *  3. Connection pool per request — new Pool/Client/neon/drizzle inside a route handler
 *  4. Missing index / full-table scan — Drizzle schema cross-reference for unindexed filters
 *  5. O(n²) nested iteration — nested for/map/forEach where inner body uses .find/.includes
 *  6. N+1 queries (Drizzle-aware) — await db./tx. inside .map(async / for loop body
 *
 * All suppressed in test, migration, seed, and script files (same guards as
 * bottleneck-detector.ts). Confidence-scored with FP guards.
 *
 * @module scanners/scale/db-antipatterns
