What:

Filter transport and browser metadata request headers out of proxy-recorded contracts and stubs.

Why:

These headers are connection or browser context metadata rather than contract-relevant inputs. Recording them in generated proxy artifacts creates noisy and brittle specifications.

How:

• Split transport header exclusions into request and response sets.
• Use the request-specific set when filtering HttpRequest headers and the response-specific set when filtering HttpResponse headers.
• Reuse the request transport header set from ProxyTest instead of maintaining a duplicate test list.
• Add proxy regression coverage for DNT, Forwarded, X-Forwarded-*, and selected Sec-* headers to ensure they are not written into recorded contracts or stubs.
