📥 Pull Request

✨ Description of new changes

Paginated report items were inconsistently treated as unsupported in the fs command matrix, blocking normal item workflows. This change onboards paginated_report where parity with report is expected.

• Support matrix updates

  • Added paginated_report to fs supported items for: mv, cp, export, import, and bulkexport.
  • Removed paginated_report from fs unsupported items for: rm, get, set, and mkdir.

• Behavior contract coverage

  • Extended hierarchy command-support tests to assert PaginatedReport support for:
    FS_EXPORT, FS_IMPORT, FS_GET, FS_SET, FS_RM, FS_MKDIR, FS_CP, FS_MV, and FS_BULKEXPORT.
