Remove redundant CloudFormationOperationsClient type alias

Clean up unnecessary type alias that was creating confusion:
- Remove: type CloudFormationOperationsClient = CloudFormationOperations
- Update: NewCloudFormationClient() to return CloudFormationOperations directly
- Clean up formatting (remove extra blank lines)

Simplifies code architecture and removes confusing indirection.
All functionality preserved, cleaner interface usage.
