onlyworlds 0.5.1

• The reader skips a dot-prefixed file in a type directory, a tool's litter rather than an element, and lists it in Folder.skipped, even when it holds a valid body. Before, it was read like any file, and one that sorted first could stand in for the real element (Skeld's clarification of the folder spec, 2026-10-17).
• Folder.time_current prefers a non-null time_current: a null one beside time_range_current now reads the range, where it read null.
