/**
 * Dependency Vulnerability Assessor
 * Detects npm/yarn/pnpm dependency vulnerabilities via package manager audits
 *
 * Implements Issue #193: Add npm/yarn dependency vulnerability detection module
 *
 * Checks:
 * - Detects package manager from lock file (package-lock.json, yarn.lock, pnpm-lock.yaml)
 * - Runs audit command: npm audit --json / yarn audit --json / pnpm audit --json
 * - Parses vulnerability counts by severity
 * - Calculates score penalty based on severity weights
 *
 * Severity Scoring (from Issue #193):
 * - critical: -10 points
 * - high: -5 points
 * - moderate: -2 points
 * - low: -1 point
 *
 * Context Requirements:
 * - sourceCodePath: Required - directory to run audit in
 *
 * Note: This module requires shell execution and is opt-in only.
