Detailed Description

Database monitoring adapter with runtime backend selection.

This adapter provides unified monitoring interface for database operations using the backend pattern for runtime polymorphism.

Available backends:

• fallback_monitoring_backend: Uses internal metrics storage (default)
• null_monitoring_backend: No-op backend for disabling monitoring

Features:

• Connection pool metrics (active, idle, usage percentage)
• Query performance tracking (latency, throughput, success rate)
• Transaction monitoring (commits, rollbacks, active transactions)
• Health checks and alerting
• Prometheus-compatible metrics export
• Runtime backend selection (no conditional compilation)
