- Centralized archive operations into a new `utils/zip.ts` module with unified support for ZIP, tar, and tar.gz formats.
- Optimized ZIP reading using lazy, ranged central-directory access and implemented ZIP64 support for large files.
- Hardened archive extraction with directory traversal protection and configured memory limits for loading and extraction.
- Refactored tool-specific logic to utilize the new centralized utility and deleted the redundant `archive-reader.ts`.
