Function create_request_with_current_span_context

pub fn create_request_with_current_span_context<T>(inner: T) -> Request<T>

Creates a new tonic::Request with the current tracing span’s context injected.

This gets the OpenTelemetry context from the current tracing span and injects it into the request metadata. Use this when forwarding requests to downstream services to ensure proper distributed tracing (child spans linked to parent spans).
