Elizabeth Interactive CLI with Tool/Function Calling

- OpenAI Chat Completions–compatible client targeting vLLM
- Provides the full Elizabeth MLOps toolkit as callable tools
- Designed for local R&D: no guardrails beyond HTTP auth

Defaults (override via flags or env):
- Base URL: http://localhost:8000/v1
- Model: qwen3-8b-elizabeth (LOCKED)
- API Key: elizabeth-secret-key-2025

Example:
  python -m mlops.elizabeth_cli \
    --base-url http://localhost:8000/v1 \
    --model qwen3-8b-elizabeth \
    --thinking chain_of_thought

While running, type your prompt and press Enter. Use commands:
  /exit        Quit
  /clear       Clear conversation
  /history     Show message count
  /system ...  Set/replace system prompt
  /save path   Save transcript to a file

This client supports tool/function calling. When the model returns tool_calls,
the CLI executes the function locally, adds the tool result back to the chat,
and continues until the model returns a normal message.
