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.
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.
