feat(artifacts): complete generic artifact system with upload handlers, tests, and action integration (#798)

- Add ArtifactUploadHandler with support for github-artifacts, storage (rclone),
  and local copy upload targets, including large file chunking for GitHub Artifacts
- Add 44 unit tests covering OutputTypeRegistry, OutputService, and
  ArtifactUploadHandler (config parsing, upload coordination, file collection)
- Add 6 new action.yml inputs for artifact configuration
- Add artifactManifestPath action output
- Wire artifact collection and upload into index.ts post-build flow
