"""
llm-connect — Pluggable LLM adapters.

Provides concrete :class:`LLMAdapter` implementations backed by
OpenRouter (HTTP), Gemini, OpenAI, and Claude Code CLI (subprocess).

Quick start::

    from llm_connect import create_adapter

    adapter = create_adapter("openrouter", model="anthropic/claude-sonnet-4")
    response = adapter.execute_prompt(prompt, run_config)
