Need Environment-Specific CORS Origin Configuration in Java Server

[dpacheco-groupieticket]

Description:

When using the Smithy-generated Java server, we need to configure CORS origins differently per deployment environment (e.g., beta vs prod). Currently, the @cors trait requires static values in the model, which doesn't support this use case.

Problem:

• Our CORS origins vary by environment (mybeta.example.com vs myprod.example.com)
• Environment variables are our standard configuration mechanism

Question:

What is the recommended approach to implement environment-specific CORS origins? If library modifications are needed, could you provide guidance on:

• Where in the codebase this would need to be changed
• Any extension points we could leverage
