Pull Request Overview

This PR optimizes memory allocation in the decorator transformation by eliminating an unnecessary temporary Vec creation. Instead of creating a vector and then immediately consuming it with extend(), the decorators are now directly extended into the target collection.

• Removes intermediate Vec allocation for metadata decorators
• Directly extends decorators into the method's decorator collection
