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

Adding the annotated message tool

* Updated architecture.md

* Added annotated-message.ts
  - registers a tool that returns a message with annotations on different content types

* In package.json
  - updated TS SDK version

   - `add` (tools/add.ts): Adds two numbers `a` and `b` and returns their sum. Uses Zod to validate inputs.
