Add an OpenAI-compatible shim (/v1/chat/completions, /v1/models) that
fulfils requests by shelling out to the local `claude` CLI in headless
print mode. Lets any OpenAI-SDK client (LLMClient, OASIS profile
generator, camel simulation) use Claude Code as the LLM without an
external API key. Stdlib-only; honors JSON mode and system prompts.
