This includes configuration options for: - Instance type selection (with dynamic and manual modes) - Region selection - SSH key management options - Smart instance inference based on cost and availability - Persistent storage configuration - OS image selection The configuration is structured with modular Kconfig files: - Main Lambda Labs configuration entry point - Compute resources (instance types) - Location settings (regions) - Identity management (SSH keys) - Storage options - Smart selection logic This provides the configuration structure but doesn't enable Lambda Labs in the provider menu yet, maintaining build stability.
