Auth Middleware Module (Go)

Composable authentication middleware module for Go HTTP services with pluggable providers. Ships with reference implementations for JWT (HS256/RS256 with JWKS), Auth0, Clerk, Supabase, and API key validation. The provider registry pattern makes it trivial to add custom auth strategies. Middleware is compatible with chi, gorilla/mux, and any net/http-based router.
