Bug: CLI Creator Parsing Splits on Commas

[debanshd]

In __main__.py, the --creator option parses 'Name[,Email[,URL]]' strings by blindly splitting on commas.

If a dataset creator is an organization with a comma in its legal name (e.g., "Google, LLC"), the name will be split and the secondary string ("LLC") will be interpreted as an email address.

Affected Location:

src/croissant_maker/__main__.py

    for creator_info in creator:
        # Parse format: "Name[,Email[,URL]]"
        parts = [part.strip() for part in creator_info.split(",")] # Dangerous!
