/**
 * PackageGate Lock File Parser
 *
 * Purpose: Extract dependency information from lock files for supply-chain vulnerability detection.
 * Based on PackageGate research (2026-01 Koi Research Team)
 *
 * Supports:
 * - package-lock.json (NPM)
 * - pnpm-lock.yaml (PNPM)
 * - bun.lockb (Bun) - basic support
