Added

Helpers - OpenTelemetry

• Explicit W3C textmap propagator - OtelUtils installs a TraceContext + Baggage composite via set_global_textmap on init and test configure (idempotent), locking traceparent / tracestate / baggage carriers.

Tests

Tests - OpenTelemetry

• Async gRPC metrics BDD - @async coverage for create_async_grpc_app rpc.server.duration, prepend order, and metrics-only mode
• Parent-chain BDD - FastAPI → gRPC hop asserts RPC span descends from GET /call-grpc
• Log ↔ trace BDD - Exported log records carry ambient trace_id / span_id
