feat: Initialize Artinet A2A SDK Project

Sets up the initial monorepo structure for the Artinet SDK, a TypeScript implementation of the Agent2Agent (A2A) protocol.

- Core project configuration (`package.json`, `tsconfig.json`, `.gitignore`).
- Initial source structure (`src/`) for client, server, types, transport, and utils.
- Basic class definitions for `A2AClient` and `A2AServer`.
- Foundational A2A schema types (`src/types/`).
- Build process configured to output ESM modules to `dist/`.
