* Remove McpServerConfig and have McpClientFactory accept IClientTransport instances directly.
* Address feedback and use lists when representing stdio arguments.
* Use "Name" for transport descriptors and "EndpointName" for MCP clients and servers.
* Update code samples.
* Fix source file naming
* Add route pattern parameter to MapMcp
* Add configureOptionsAsync
* Use Kestrel for all in-memory HTTP tests
* Use ApplicationStopping token for SSE responses
* Use RegisterNotificationHandler in MapMcp tests
* Work around SocketsHttpHandler bug where it doesn't call DispseAsync on the stream returned by the ConnectCallback
- We still allow notification handlers to be configured pre-creation, eliminating any race conditions that may result from missed notifications. But now we also allow for post-creation notification handler registration.
- Handlers may now also be removed. This permits temporary registrations that may be created in a scoped manner.
- Registration handling is thread-safe.
- Handlers are now cancelable.
- Exceptions from notification handlers trigger all normal exception handling in the dispatch pipeline.
This also:
- Adds a WithStreamServerTransport as a counterpart to WithStdioServerTransport. The latter was used in several tests in a hacky way, and that's now simplified via the former's existence.
* Move notification handler registrations to capabilities
Currently request handlers are set on the capability objects, but notification handlers are set after construction via an AddNotificationHandler method on the IMcpEndpoint interface. This moves handler specification to be at construction as well. This makes it more consistent with request handlers, simplifies the IMcpEndpoint interface to just be about message sending, and avoids a concurrency bug that could occur if someone tried to add a handler while the endpoint was processing notifications.
* Address more feedback and further cleanup
* Allow user-defined JsonSerializerOptions for user-defined and inputs and hardcode everything else to the source generator.
* Add validation for user-defined JsonSerializerOptions.
* Remove out of date comment.
* Address feedback and add tests
* Move WriteJsonRpcMessageToBuffer to method
* Fix indentation in McpClient
* Make supposedly unreachable code less reachable
* Guard against multiple RunAsync calls
* Move RunAsync inside of Try in MapMcp
* Add ModelContextProtocol.AspNetCore
- Remove IServerTransport and HttpListenerSseServerTransport
- Replace HttpListenerSseServerTransport usage in tests with ASP.NET Core.

* Improve progress reporting
- Enable injecting an `IProgress<>` into a tool call to report progress when the client has supplied a progress token
- Add a custom type for ProgressToken and ProgressNotification to map to the schema
- Simplify RequestId to match ProgressToken's shape
- Serialize StdioClientTransport's SendMessageAsync implementation
- Add strongly-typed names for all request methods
- Change all request IDs created by McpJsonRpcEndpoint to include a guid for that endpoint
* Address PR feedback
- This also paves the way for better multi-session support
- We should definitely rethink names for the transport API
- For now, I kept the names similar as possible, so we can
focus on the API shape

* 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.
