Replace XML-style markup tags in comments with markdown equivalents: - <code>...</code> to `...` (inline code) - <tt>...</tt> to `...` (teletype/monospace) - <i>...</i> to *...* (italics/emphasis) - +...+ to `...` (parameter/variable references) Updated 80+ files across core source, headers, mrbgems, and libraries to use consistent markdown formatting in documentation comments. Handled edge cases including special characters like <=> operators. Co-authored-by: Atlassian Rovo Dev
