HWANG BYUNGHA 184054c6c1 Initial commit: Vultr API v2 Python wrapper with FastAPI server
- vultr_api/: Python library wrapping Vultr API v2
  - 17 resource modules (instances, dns, firewall, vpc, etc.)
  - Pagination support, error handling

- server/: FastAPI REST server
  - All API endpoints exposed via HTTP
  - X-API-Key header authentication
  - Swagger docs at /docs
