Sync roots at startup. This was deferred to list_roots tool is used, but I'm putting it back.

The syncRoots call should be idempotent, requesting roots if they haven't been yet for the session, but always retuning the cached roots otherwise. That could be deferred but setting the handler for roots_list changed note should not.

* In server/roots.ts
  - only set the notification handler and call for initial roots list if the roots aren't already cached for this client.

* In server/index.ts
  - in the oninitialized handler
    - get the sessionId from the transport
    - set a 350ms timeout to call syncRoots with the server and sessionId
      - this delay cause it to run after the `notifications/initialized` handler finishes, otherwise, the request gets lost.

* All other changes attributable to prettier
