gossan-techstack 0.3.1

//! Competitor benchmark — gossan-techstack vs projectdiscovery/httpx
//! and webanalyze.
//!
//! Both peer tools fingerprint the tech stack of an HTTP target.
//! We can't legitimately run head-to-head without a live HTTP
//! fixture (which would require a docker-compose with N stack
//! variants). For this test we (a) verify peer binary presence and
//! (b) skip the actual run with a clear install hint.
//!
//! Note: the python `httpx` (HTTP client library) is unrelated to
//! projectdiscovery's Go `httpx` and shadows the binary on most
//! systems. We resolve the Go binary explicitly via `~/go/bin/httpx`.
