[WIP] Refactor everything server to be more modular and use recommended APIs.

Browse Source 
Added tools to toggle simulated logging and resource updates on and off rather than have them start immediately upon connection

* Updated architecture.md

* In server/index.ts
  - remove import of beginSimulatedResourceUpdates and beginSimulatedLogging
  - remove clientConnected from createServer factory result

* In tools/index.ts
  - import registerToggleLoggingTool and registerToggleSubscriberUpdatesTool
  - in registerTools
    - call registerToggleLoggingTool and registerToggleSubscriberUpdatesTool

* In logging.ts
  - in beginSimulatedLogging
    - refactor extract inline interval callback into function sendSimulatedLoggingMessage
  - call sendSimulatedLoggingMessage right away to send the first message
  - supply sendSimulatedLoggingMessage as interval callback

* In subscriptions.ts
  - remove import of Transport
  - remove transports map
  - in beginSimulatedResourceUpdates()
    - change arguments to server and sessionId
    - check for the subsUpdateInterval for the session
    - remove all transport storage and interaction
    - instead use the server to send the notification
 - in stopSimulatedResourceUpdates()
   - remove management of transports map

* In stdio.ts, sse.ts, and streamableHttp.ts
  - remove destructure and calling of clientConnected

* Added tools/toggle-logging.ts
  - registers a tool that
    - takes no arguments
    - tracks clients that have been enabled by session id in a set
    - if client isn't enabled,
       - calls beginSimulatedLogging
       - adds session id to client set
    - else
      - calls stopSimulatedLogging
      - deletes session id from client set
    - returns a message explaining what was done including what to expect when logging is enabled

 * Added tools/toggle-subscriber-updates.ts
   - registers a tool that
     - takes no arguments
     - tracks clients that have been enabled by session id in a set
     - if client isn't enabled,
        - calls beginSimulatedResourceUpdates
        - adds session id to client set
     - else
       - calls stopSimulatedResourceUpdates
       - deletes session id from client set
     - returns a message explaining what was done including what to expect when logging is enabled
