Replace the old RunShutdown and RunTLS style entry points with a single Run(opts...) API for v1. Add focused startup semantics tests, keep TLS and graceful shutdown independent, ensure sibling servers are cleaned up on startup failure, and update docs to match the new option-based startup model.
Clarify that outgoing proxy queries are normalized before forwarding, which may re-encode or drop non-standard fragments to keep parsing behavior consistent across proxy chains.
Preserve final headers when forwarding 1xx responses, reject invalid 101 upgrade negotiations, and make the default Via token RFC-safe. Tighten the reverse proxy tests around goroutine synchronization and document the Via fallback behavior more clearly.
Document BufferPool usage and explain why trailer fallback and disconnect compatibility logic intentionally mirror the standard library reverse proxy. Add a regression test covering unannounced trailer forwarding so that proxy trailer behavior stays aligned with Go's semantics.
Provide an RFC-aware reverse proxy handler so Touka services can forward normal, streaming, and upgraded HTTP traffic without leaving the framework. Document the new API and proxy-chain behavior so deployments behind other gateways preserve forwarding metadata correctly.
