* feat: add OpenAI-compatible HTTP API (/v1/chat/completions, /v1/models)
* - Reject model mismatches: validate req.model against the active model
and return 404 model_not_found instead of silently ignoring it
- Add x-ironclaw-streaming: simulated response header so clients know
streaming is not true token-by-token delivery
- Use SSE event type "error" for mid-stream LLM failures so clients can
distinguish errors from content chunks
- Mark docker-compose credentials as dev-only
- Add integration tests for model mismatch, streaming header, and body
size limit (axum's default 2MB)
* fix: address Copilot review feedback on OpenAI-compat API
- Wire chat_rate_limiter into /v1/chat/completions handler
- Execute LLM before starting SSE stream so failures return proper HTTP
errors instead of SSE error events
- Validate tool-role messages require tool_call_id and name fields
- Surface list_models() errors in models_handler via map_llm_error
- Reject unknown roles with 400 instead of defaulting to User
