add-prompt-enhancement-guide

Author a prompt-enhancement system prompt for a new ecosystem and register/update it on the orchestrator's prompt-analysis service. Use when onboarding a new ecosystem (e.g. happyhorse, a new Flux variant, a new Wan video version) and the user provides the ecosystem key plus a reference link, model card, or description. Produces a guide that mirrors the structure and tone of existing ecosystem guides so the prompt-analysis tool behaves consistently.
