/**
 * Async Task Scheduler
 *
 * Schedules asynchronous tasks after transaction completion.
 *
 * Key features:
 * 1. Queueing: Add async tasks to queue
 * 2. Background execution: Execute in background after transaction commit
 * 3. Error isolation: Async task failures don't affect main logic
 * 4. Logging: Log execution status

     *
     * 1. Test environment: Always OFF (for clean test output)
     *    - NODE_ENV=test → No logs
     *
     * 2. Explicit control (highest priority):
     *    - FEATURE_LOGS=true → Force ON (any environment except test)
     *    - FEATURE_LOGS=false → Force OFF (any environment)
     *
     * 3. Default behavior (when FEATURE_LOGS not set):
     *    - development → ON (helpful for debugging)
     *    - production → OFF (clean production logs)
