Function init 

pub fn init()

Initialize the Prax logging system.

This should be called once at application startup. Subsequent calls are no-ops.

Logging is controlled by:

• PRAX_DEBUG=true - Enable debug-level logging
• PRAX_LOG_LEVEL - Override the log level (trace, debug, info, warn, error)
• PRAX_LOG_FORMAT - Output format (pretty, json, compact)

Example

use prax_query::logging;

// Initialize at the start of your application
logging::init();
