fix(server): remove initialized notification gate to support Streamable HTTP (#788)
* fix(server): remove initialized notification gate to support Streamable HTTP

The server's init handshake loop fatally rejected any request arriving
before the `notifications/initialized` message. This breaks Streamable
HTTP clients where each JSON-RPC message is a separate POST with no
ordering guarantee — `tools/list` can easily arrive before `initialized`.

Remove the ~40-line wait loop and enter `serve_inner` immediately after
sending `InitializeResult`. The `initialized` notification is now
handled as a regular notification by the main service loop, matching the
TypeScript SDK behavior (validated in typescript-sdk#578).

Also remove the now-unreachable `ExpectedInitializedNotification` error
variant from `ServerInitializeError`.

Closes #783

* fix(server): keep ExpectedInitializedNotification as deprecated

Retain the variant for semver compatibility — removing it would be a
breaking change caught by cargo-semver-checks. Mark it deprecated with
a note that it is never constructed and will be removed in a future
major release.
