Implements Fix 4 of the wiki-links-and-search-followup spec (plugin repo). Removes the {{{ if ./isMainPost }}} fa-book fallback branch from templates/partials/posts_list_item.tpl — it put a book icon on every global-search result title. Only the isWikiArticle badge remains.
Deliberate blast radius: the partial also serves the seven account/profile post lists, which lose the marker too (restores pre-PR-#14 appearance). search-results.tpl untouched; its badge lights up once the companion plugin PR (fix/wiki-links-search-followup) delivers the flags.
Contract test extended to pin the removal; passing.
