Add v1-compat re-exports: `StreamableHTTPServerTransport` (alias for `NodeStreamableHTTPServerTransport`) and the `EventStore` / `EventId` / `StreamId` types, so v1 imports from `@modelcontextprotocol/sdk/server/streamableHttp.js` map cleanly onto `@modelcontextprotocol/node`.

Not sure if the direction is right - EventStore is already exported from '@modelcontextprotocol/server' and the premise of the node middleware package isn't that users should only work with it.

They should be importing both the node middleware, and the server package. In which case they already have the access readily to them from the server package.
