Detailed Description

DICOM query result cache with monitoring integration.

This file provides a specialized cache for DICOM C-FIND query results that integrates with the PACS monitoring system for metrics reporting.

The query_cache wraps simple_lru_cache and adds:

• Integration with pacs_metrics for hit/miss/eviction tracking
• Integration with logger_adapter for cache event logging
• Helper methods for building cache keys from query parameters
