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.
