 * Everything is loaded and hooked: the moment for an add-on to start.
 *
 * Silotree's extension points are plain WordPress hooks, and each one is inert when nothing is
 * listening: the screens look and work the same with or without an add-on. The ones there are:
 *
 * - silotree_loaded: this action, once, with every class defined.
 * - silotree_admin_menu: inside Silotree's admin_menu, after Broken links, to add screens to the
 *   Silotree menu. Gets the parent slug.
 * - silotree_report_bulk_actions (filter, array of action => label) and silotree_report_bulk
 *   (action: $action, int[] $post_ids): batch actions on the posts-nothing-links-to report. With no
 *   actions, the report has no checkboxes at all.
 * - silotree_broken_bulk_actions (filter) and silotree_broken_bulk (action: $action, array[] of
 *   from_post and url): the same for Broken links. silotree_broken_row_actions (filter: markup
 *   strings, $row) adds a button to one row beside "Fix in editor".
 * - silotree_editor_assets (action: $post, $block_editor): after the editor's scripts are queued,
 *   to add one that extends them. The publish prompt reads two wp.hooks filters,
 *   silotree.publishPrompt.rowControl and silotree.publishPrompt.footer.
 * - silotree_settings_cards (action) and silotree_settings_actions (filter: null or a notice) on
 *   Silotree, Settings.
 * - silotree_batch_label (filter: $label, $batch_id): what Undo history calls a batch.
 * - silotree_builder_written (action: int $post_id, SiloTree_Store $store): after Silotree wrote,
 *   or undid, a page builder's own data for a post, for a cache or CDN plugin to purge that page.
 * - silotree_click_rate_limit (filter: int, default 600): counted link clicks a minute, site-wide.
 * - silotree_screen_top (action: 'reports' or 'broken'): under the heading of those screens, for
 *   an add-on's result banner.
 *
 * Undo never depends on an add-on: every batch, whoever wrote it, is recorded and taken back by
 * SiloTree_Apply in this plugin.
