Lightweight C++23 S3 client with no extra deps (just curl and OpenSSL)

A lightweight C++23 S3 client library with zero dependencies beyond libcurl and OpenSSL, designed for developers who need minimal S3 integration without heavy SDKs. It provides basic S3 operations tested primarily against MinIO, making it ideal for simple local or embedded storage use cases. The project is interesting for its extreme minimalism and focus on C++23 features, though users should expect potential compatibility issues with AWS S3.
