feat: Initialize test-ai-sdk project with Bun

- Add README.md with installation and usage instructions.
- Create bun.lock and pnpm-lock.yaml for dependency management.
- Implement main functionality in index.ts to test AI providers.
- Add opencode.json configuration for various AI providers.
- Create package.json to define project dependencies and scripts.
- Add TypeScript configuration in tsconfig.json for project setup.
- Implement test scripts for different AI providers in src directory.
