fix(service-ai): remove unsupported 'author' field from package tools

ManifestSchema does not include an 'author' field, causing TypeScript compilation error.
Removed 'author' from:
- create_package tool parameter definition
- createCreatePackageHandler args extraction
- createGetPackageHandler response
- manifest object construction
