Add Posts and Replies block using query_loop_block_query_vars#3036
Conversation
Alternative approach to #1213: instead of running custom queries, this block renders a tab bar that controls a sibling core/query block via the `query_loop_block_query_vars` filter. The "Posts" tab (default) filters out posts containing the `activitypub/reply` block. The "Posts & Replies" tab shows all posts. Tab state is managed via a URL parameter (`?ap_tab=`), so pagination and the Query Loop block work naturally without custom query logic. This preserves full core/query customization in the Site Editor. Related: #1213

[Focus] Editor
- Replace ARIA role="tab" with nav + aria-current="page" since tabs are navigation links (page reloads), not JS-controlled panels. - Reset pagination when switching tabs to avoid out-of-range pages. - Use focus-visible instead of focus for cleaner keyboard indication.

Pull request overview
Adds a new “Posts and Replies” block intended for author archive templates that provides a tab UI and filters the adjacent Query Loop via query_loop_block_query_vars, avoiding a custom WP_Query so users retain full Site Editor control over layout.
Changes:
- Introduces
activitypub/posts-and-repliesblock (editor placeholder + server-rendered tab bar + styles). - Hooks
query_loop_block_query_varsto conditionally exclude “reply” posts by adding aposts_whereclause. - Updates the plugin’s Fediverse author archive template to include the new block above the Query Loop.

query_loop_block_query_vars never fires when the Query Loop uses inherit:true — it clones the global WP_Query directly, skipping build_query_vars_from_query_block() entirely. Switch to pre_get_posts on the main query so the reply exclusion filter applies to inherited queries on author archives.
