Fix some issues with Native AOT (#130)

* Fix some issues with Native AOT

- An anonymous type was being used in McpClient for the initialize result message. Switched to use the type for that purpose that already existed.
- A bunch of the request params / result types were not in the source context or referenced from types that were or from custom converters. Added all the request/result types to the context.
- Improved the warning message for WithTools.
