Generate per-platform PipelineTasks with architecture-specific nodeSelectors so each build runs on a matching node. Source code is bundled as an OCI artifact during source-acquisition and pulled on each platform node. Per-platform tasks suffix the output image tag with the platform to prevent registry GC from deleting intermediate images. After all platform builds complete, an assemble-index task creates an OCI image index referencing each platform image. Result aggregation populates BuildRunStatus.PlatformResults with per-platform digest, size, vulnerabilities, and status, and sets ManifestDigest and Output.Digest to the index digest. Partial failure is tracked per platform so users can identify which architecture failed. CLI flags --push-source-bundle and --assemble-index are added to the image-processing binary, consumed by the source-acquisition and assemble-index pipeline tasks respectively. Closes shipwright-io#2143, closes shipwright-io#2076 Assisted-by: Cursor Signed-off-by: Anchita Borah <anborah@redhat.com>
