Replace simple prefix stripping with proper scheme extraction logic - Mimic stereoscope.ExtractSchemeSource behavior exactly like syft CLI does - Extract valid schemes (file:, docker:, registry:, etc.) and pass stripped input to syft - Leave invalid or missing schemes unchanged (e.g., nginx:latest stays as-is) - Supports all syft source provider schemes: file, dir, docker, podman, containerd, registry, docker-archive, oci-archive, oci-dir, singularity This matches syft's exact behavior where both 'file:path' and 'path' work identically.
