feat: add security sink detection patterns for JavaScript/TypeScript
- Introduced `sink-detect.js` with various security sink detection patterns categorized by type (e.g., command injection, SQL injection, file operations). - Implemented functions to build a lookup map for fast sink detection and to match sink calls against known patterns. - Added `package-lock.json` for dependency management.
