Pull request overview

Exposes CallerDetails (non-agentic caller identity metadata) on the ExecuteTool and Inference tracing scopes and ensures the same metadata flows into ETW/exporter payloads and DTO builders, with corresponding test coverage.

Changes:

• Add optional callerDetails propagation into InferenceScope and ExecuteToolScope (via OpenTelemetryScope).
• Extend ETW logging and DTO builders to include caller attributes (id/name/upn/client ip/tenant id).
• Add/extend unit and integration tests validating caller tags/attributes across tracing, ETW, and exporter paths.
