Thanks for the PR. This has since landed via #2381. Closing as part of a general backlog cleanup following the v2 release. If this is still relevant against v2, feel free to reopen. |

Part of #421
Motivation and Context
This implements OpenTelemetry context forward propagation (if available) through _meta, as specified in
MCP C# SDK has a similar implementation: https://github.com/modelcontextprotocol/csharp-sdk/blob/v0.8.0-preview.1/src/ModelContextProtocol.Core/Diagnostics.cs#L64. This is working for normal client to server calls, and for server calls back to the client like MCP Sampling.
How Has This Been Tested?
