Add comprehensive skill for building, testing, and debugging Hermes Agent
RL environments for Atropos training. Includes:
- SKILL.md: Full guide covering HermesAgentBaseEnv interface, required
methods, config class, CLI modes (serve/process/evaluate), reward
function patterns, common pitfalls, and minimum implementation checklist
- New 'Inference Setup' section: instructs the agent to always ask the
user for their inference provider (OpenRouter + model choice, self-hosted
VLLM endpoint, or other OpenAI-compatible API) before running tests
- references/agentresult-fields.md: AgentResult dataclass field reference
- references/atropos-base-env.md: Atropos BaseEnv API reference
- references/usage-patterns.md: Step-by-step patterns for process,
evaluate, serve, and smoke test modes
