コントラクト
- assert Base64.urlsafe_encode64 includes '=' padding by default and requires padding: false to emit unpadded strings
- assert Base64.urlsafe_encode64 translates '+' to '-' and '/' to '_'
- assert Base64.urlsafe_decode64 natively decodes both unpadded and correctly padded urlsafe strings without manual padding calculation
- assert Base64.decode64 silently strips '-' and '_' without error leading to truncated or empty outputs
- assert Base64.strict_decode64 rejects urlsafe characters '-' and '_' with ArgumentError
- assert Base64.urlsafe_decode64 rejects malformed lengths and incorrect padding counts with ArgumentError
