Add DEFLATE decompression support to ZIP parser

- Add Bun.decompress() support for compression method 8 (DEFLATE)
- Properly decompress ZIP files instead of returning compressed data
- Fix JSON parsing errors for metadata.json
- Handle decompression errors gracefully with fallbacks
- Remove compression method warnings for supported formats
