Mandatory RPM provenance for SingleInstance Database images.

Generates:

• base-image-rpms.txt — RPMs from the Oracle Linux base image
• image-rpms.txt — all RPMs in the final image
• image-added-rpms.txt — RPMs added beyond the base image

Base-image provenance:

• /usr/share/oracle/image-metadata/base-image-chain.json
• OCI image labels point to this file.
• Base-image identity is recorded separately from the RPM inventory.

SingleInstance image layout:

• Versions 19.3.0 and later use containerfiles//Containerfile.
• Legacy versions continue using dockerfiles//Dockerfile.
• Build scripts select the appropriate layout automatically.

Build updates:

• SingleInstance build wrappers prefer Podman.
• Docker remains the fallback when Podman is unavailable.
• SingleInstance setup scripts update DNF metadata and clean package caches.

Documentation includes commands for inspecting the base-image chain and RPM reports inside the built image. No additional INCLUDE_RPM_METADATA build argument is
required.
