Crisis Gateway Module for the-door.

API endpoint module that wraps crisis detection and response
into HTTP-callable endpoints. Integrates detect.py and response.py.

Usage:

    result = check_crisis("I don't want to live anymore")
    print(result)  # {"level": "CRITICAL", "indicators": [...], "response": {...}}
