* 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

* 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.
