Debug logging utilities for Nexlm requests and responses.

Enables detailed logging of HTTP requests and responses to help with debugging provider integrations, caching behavior, and other issues.

Or set the environment variable:

Log Output

When enabled, logs will include:

• Provider being called
• Full HTTP request (method, URL, headers, body)
• Full HTTP response (status, headers, body)
• Request/response timing
• Any transformations applied to messages
