* fix(web): replace mermaid bomb-icon error flood with toast notifications mermaid.render() called without a container leaves orphaned error elements (with bomb icons) in document.body on parse failures. Clean up these orphans after every render and show an error toast instead. * fix(web): address PR review — prevent toast flooding, include error detail, add hook tests - Add latestRenderId guard in TipTap MermaidNodeView to skip stale renders, preventing toast spam on every keystroke - Include mermaid error message in toast description via CustomEvent detail - Add useMermaidErrorToast hook tests (event listener + cleanup) * style(web): format mermaid-error-toast test with prettier * fix(web): include error message in MermaidBlock toast description
