Enumeration MetricName

Typed metric name constants for MCP server and EP API instrumentation.

Using an enum prevents typos in metric names and enables IDE auto-complete throughout the codebase.

metricsService.incrementCounter(MetricName.EP_API_CALL_COUNT, 1);
metricsService.incrementCounter(MetricName.EP_CACHE_HIT_COUNT, 1);
