C3D-0386 · Move PROJECT_BOUNDARY_TEXT to SS-0-FRAME and delete the layer [C3D-PBTMOVE] done

Moves all top-level entities on PROJECT_BOUNDARY_TEXT to SS-0-FRAME, sends any in-block guts to 0, then deletes the emptied PROJECT_BOUNDARY_TEXT layer. Verifies SS-0-FRAME's new count.

// In-block guts go to 0 (stay connected); top-level goes to SS-0-FRAME.
