callonce-go – singleflight and per-request caching for Go services

The Take
Combines singleflight with a context-scoped per-request cache so concurrent and subsequent callers share one in-flight call and instant cached results, respectively. Typed Key[T] generics and a tiny API (WithCache/Get) make it trivial to add to middleware, and the zero-allocation claim targets the micro-optimizations Go teams care about.
