Let Everything's STDIO server use SDK's automatic log level handling (#2706)

- bump TS SDK to 1.18.0
* In src/everything/stdio.ts
  - remove logging related imports
  - remove custom log-level handling, now handled automatically by the SDK
* In src/everything/everything.ts
  - remove console.log of sessionId
