feat: Add Windows Docker Desktop support for local development

- Detect Windows platform and use named pipe (//./pipe/docker_engine)
  instead of Unix socket for Docker Desktop compatibility
- Add NOMAD_STORAGE_PATH environment variable for configurable
  storage paths across different platforms
- Update seeder to use environment variable with Linux default
- Document new environment variable in .env.example

This enables local development on Windows machines with Docker Desktop
while maintaining Linux production compatibility.
