Research direction

Start at the CLI argument parsing entry point and compare the existing --model and model_reasoning_effort handling. Verify that --luna, --sol, and --terra resolve to the current generation and requested tier when available, and produce an error otherwise; confirm the expanded form remains equivalent.
