NetHack agent harness with benchmarks and livestream

You can watch an LLM play NetHack step-by-step with the model's reasoning, the exact action code, and a live game canvas — that instrumentation is the product's real selling point. The leaderboard + run/benchmark framing makes it useful for comparing agents rather than just a flashy demo, but it's still squarely for people who care about NetHack or agent evaluation; more detail on reproducible metrics and integrations would push it further.
