Detailed Description

HTTP-level integration test for the prometheus-cpp backend.

Records metrics through prom's client-independent API, serves them from a real prometheus::Exposer (the Civetweb-backed pull endpoint a host application uses), then scrapes /metrics over an actual TCP/HTTP round trip and asserts the exposition text came back intact. Unlike the in-process serializer tests, this exercises the full pull path end to end over a socket.

POSIX sockets only (the CI matrix is Linux + macOS); guarded accordingly so the file is simply skipped elsewhere.
