Fix ZIP deployment integration with custom ZIP parser

- Fix import paths in _kv.ts to resolve module resolution errors
- Implement custom ZIP file parser using DataView and ArrayBuffer
- Replace zipFile.entries() with Bun-compatible ZIP parsing
- Add comprehensive debugging for ZIP loading process
- Maintain backward compatibility with legacy msgpack format
