Http-tower-hs — A Rust Tower-inspired middleware library for Haskell

Also wanted to share a real-world usage example: sentinel, a small infrastructure health monitor built on top of http-tower-hs. Each probe builds its own middleware stack from config (timeout, retry, circuit breaker, redirect following, header injection, OpenTelemetry tracing), only enabling what’s configured. The README has a full middleware ordering sectionshowing how the code maps to the YAML config. It was a useful real-world test of the API. If anything felt awkward, it showed up quickly.
