<p dir="auto">This PR updates the <code class="notranslate">RichText#linkify_users</code> method to support user mentions containing spaces by allowing quoted syntax (e.g., <code class="notranslate">@"Open Mapper"</code>).</p>
<p dir="auto"><strong>Key changes:</strong></p>
<ul dir="auto">
<li><strong>Updated Regex:</strong> Now detects mentions enclosed in quotes.</li>
<li><strong>Quote Handling:</strong> Supports straight quotes (<code class="notranslate">"</code>), smart quotes (<code class="notranslate">“”</code>), and escaped entities (<code class="notranslate">"</code>), ensuring compatibility with the Markdown renderer.</li>
<li><strong>Email Protection:</strong> Added a negative lookbehind <code class="notranslate">(?<!\w)</code> to ensure that email addresses (e.g., <code class="notranslate">user@example.com</code>) are not accidentally parsed as mentions.</li>
<li><strong>Prevented Double-Linking:</strong> The visible <code class="notranslate">@</code> symbol is replaced with the HTML entity <code class="notranslate">@</code> to prevent subsequent parsers (like <code class="notranslate">expand_link_shorthands</code>) from detecting the mention a second time.</li>
</ul>
<h3 dir="auto">How has this been tested?</h3>
<ul dir="auto">
<li><strong>New Test Case:</strong> Added <code class="notranslate">test_linkify_username_with_space</code> to <code class="notranslate">test/lib/rich_text_test.rb</code> to verify that quoted mentions are correctly parsed into relative links with safe HTML output.</li>
<li><strong>Regression Testing:</strong> Ran the full <code class="notranslate">RichTextTest</code> suite (<code class="notranslate">bundle exec rails test test/lib/rich_text_test.rb</code>) to confirm that standard mentions (<code class="notranslate">@user</code>) and email addresses still function correctly.</li>
<li><strong>Linting:</strong> Verified code style compliance using <code class="notranslate">rubocop</code>.</li>
</ul>
