- Change podman-env to use Docker client against Podman's Docker-compatible socket
- Remove SSH-based connectivity (Docker client doesn't support SSH keys)
- Simplify podman-env to use standard Docker environment variables
- Update tests to match new Docker API compatibility approach
- Update documentation to clarify Docker client usage
- Remove podman-specific test cases from docker-env_test.go
This addresses the core review feedback about API compatibility issues
and provides a cleaner separation between docker-env and podman-env.
