Structured Logging

Production logging patterns for Python services. Replace stdlib logging with structured, machine-parseable output that integrates with Grafana Loki.

Setup: loguru + structlog

# src/coremind/core/logging.py
import structlog
from loguru import logger
import sys
import json

def setup_logging(json_output: bool = True, level: str = "INFO"):
    """Configure structured logging for CoreMind services."""

    # Remove default loguru handler
    logger.remove()
