/**
 * @module adapters/console-logger
 *
 * High-performance console logger inspired by pino's design:
 * - Numeric level comparison for O(1) gating
 * - stdout.write() in production for raw JSON lines (no console overhead)
 * - Colorized single-line output in development
 * - No-op method replacement when level is above threshold
 * - Child logger support with merged bindings

 * CloudWatch, Datadog, and other structured log ingestion systems).
 *
 * Development mode emits colorized, human-readable output.
