2.13.0

• Event categories in the calendar are links again, pointing at their archive. The previous calendar linked them, those URLs are public and indexed, and this taxonomy claims the same base -- rendering the names as plain text quietly dropped a working route rather than simplifying one.
• Category archives get a layout. Without one a theme prints excerpt fragments and pagination and nothing that identifies an event, which is the same failure single event pages had before 2.7.0 and matters more here, because those URLs were already being linked from every row of the old calendar. The archive renders the calendar shortcode filtered to the term, so there is one renderer rather than two that can drift, and it inherits load-more, month dividers and collapse. It shows upcoming dates only, matching how the archive is already ordered.
• A theme template named taxonomy-abm_category.php still wins, and the Event Pages setting switches both templates off together.
