fix(csharp): address PR review feedback - test isolation, assertions, resource cleanup
- Restore AsyncLocal for ExporterOverride to prevent parallel test interference - Add missing IsInternalCall assertion in InternalCallTests - Replace silent-pass with Skip.If when no telemetry captured in baseline tests - Use await instead of .Result for async calls in MetadataOperationTests - Add TimestampMillis to metadata operation telemetry Context - Cache Process.GetCurrentProcess() call in BuildSystemConfiguration - Move reader disposal to finally blocks in ChunkMetricsReaderTests Co-authored-by: Isaac
