OpenTelemetry Instrumentation Extension

Add OpenTelemetry instrumentation by applying the defer pattern for new operations within pkg/telemetry and cmd/docker-mcp. This ensures consistent telemetry coverage for state-changing changes through automated metrics and tests.

Update telemetry when changes introduce new operations or modify state within pkg/telemetry and cmd/docker-mcp. Instrumentation is required to maintain consistent metrics coverage and validate functionality through tests.

The defer pattern for OpenTelemetry metrics is a standardized instrumentation approach applied to new operations in pkg/telemetry. It ensures telemetry coverage is consistently applied and verified through tests.

Validate OpenTelemetry metrics by running generated tests and checking the OTEL collector after applying the defer instrumentation pattern. Update documentation per the telemetry README to verify coverage.

Yes, the MCP Gateway telemetry instrumentation requires updating existing tests. The process generates tests and updates documentation per the telemetry guidelines to validate the new metrics.

Instrumentation applies strictly to new operations and state modifications within pkg/telemetry and cmd/docker-mcp. Changes outside these packages or not involving state modifications do not require this telemetry coverage.
