Problem: category_view had no fold support, making it harder to focus on one category in large lists. Solution: add M.get_fold() returning '>1' for headers, '1' for task lines, and '0' for blanks. M.render() now sets foldmethod=expr (foldlevel=99) in category view and foldmethod=manual in priority.
