fix: forward the negotiated protocol version to the remote backend transport ...
The web client's SDK Client owns the `initialize` handshake, so the
`setProtocolVersion()` call it makes after initialize lands on
RemoteClientTransport — a pass-through to the Node backend, not the real
HTTP transport. The backend's StreamableHTTPClientTransport therefore never
learned the negotiated version and stamped no `Mcp-Protocol-Version` on any
request after initialize, starting with `notifications/initialized`. A
stateful server that requires the header rejects that notification with
HTTP 400.
RemoteClientTransport now records the version and rides it on every
`/api/mcp/send`; the backend applies it to its transport before the send, so
that request and everything the transport issues afterwards (the standalone
SSE GET, the session DELETE) carry the header. The version is validated
against a token pattern on the backend so a client can't push arbitrary
bytes into an upstream header.
