Package name should be lower case

Error message

Package name should be lower case

What it means

Naming-rule guard in CargoPackHandler.publish: the package name in the uploaded metadata is not lower case, but cargo registry names must be lower case; ClientException 400 rejects the publish. Fix: publish with an all-lower-case package name.

Solutions

1. Lower-case the package name in Cargo.toml (cargo convention requires lowercase).
2. Normalize the name in the publish payload before uploading.
