google-labs-jules[bot] 5a864a9059 feat: Add optional compression to collect commands
This change introduces optional compression to the `collect` commands. Users can now specify `--compression` with `gz` or `xz` to compress the output. The `serve` command has also been enhanced to transparently decompress and serve these files.
