Proxy / Traffic Interceptor

> ℹ️ _This issue was partially AI-generated and may contain technical inaccuracies._

**Is your feature request related to a problem? Please describe.**
Documenting or reverse-engineering an existing API means re-creating every request by hand.

**Describe the solution you'd like**
Provide a proxy / traffic interceptor that captures HTTP traffic from the browser or another app and imports the captured calls directly as Trufos requests.

**Describe alternatives you've considered**
Manual recreation of requests; importing from HAR files exported by browser devtools.

**Additional context**
Postman-exclusive feature. Raises trust/security considerations (TLS interception, certificate handling) that must be designed carefully.

No files, tests, or entry points are named. Start by clarifying capture requirements for browser or other-app traffic and how captured calls become Trufos requests, using HAR import as the stated alternative. Define TLS interception, certificate handling, and security acceptance criteria before implementation.
