fix: skip author field in Package entity

[koki-develop]

Closes #126

• Modified the Package struct to skip the author field to resolve an issue where a User was being automatically created when creating a Package
• Added an author_id field to ensure the author_id column is still created in the Package table (for backward compatibility)
• After looking through the source code, I couldn't find where author_id is actively used, so this change should not affect existing behavior
  • When getting for a package's author, the user_id is used instead (not author_id)
    • https://github.com/koki-develop/vpm/blob/d81991115af5367cdd8443e09c679efdff04f654/src/usecase/package/packages.v#L98

To be honest, I'm not that familiar with vlang so I'm not sure if this approach is correct, but it solved the problem at least locally.

Thanks a lot for this! I have no idea why it stopped working all of a sudden. Wasn't an issue before. Perhaps a change in ORM.

Need to add it to CI. (adding new modules to vpm)

Thank you for merging!
Has this fix been reflected on vpm.vlang.io? The issue still seems to persist.

[medvednikov]

Yes, it's been fixed. I've just deployed it, and it works great.
