OpenEnv wrapper — registers SpindleFlowEnv as an OpenEnv-compatible environment.

HACKATHON REQUIREMENT: OpenEnv (latest release) must be used.
This module makes SpindleFlowEnv discoverable and instantiable via the
OpenEnv registry, satisfying the minimum submission requirement.

Usage:
    import env.openenv_wrapper  # triggers registration
    import openenv
    env = openenv.make("SpindleFlow-v0")
