fix(agents): normalize single newlines to markdown paragraphs in quiz content#441

Conversation
… content LLMs often emit single \\n characters between logical paragraphs in question / answer / explanation fields. In markdown this renders as a soft-break, causing the front-end to collapse everything into one dense block. Add _normalize_markdown_paragraphs() to Generator so that isolated single newlines are turned into \\n\\n paragraph breaks before the payload is returned. Structural markers (lists, code fences, tables, headings) are preserved to avoid breaking intentional formatting. Fixes quiz questions appearing without paragraph spacing in the web UI.

Description
Fix quiz question content not rendering with proper paragraph spacing in the web UI.
LLMs often emit single
\ncharacters between logical paragraphs inquestion,correct_answer, andexplanationfields (e.g.(1)…(2)…). In Markdown, a single newline is treated as a soft-break and rendered as a space, causingreact-markdownto collapse everything into one dense<p>block.This PR adds
_normalize_markdown_paragraphs()to theGeneratorclass so that isolated single newlines are converted to\n\nparagraph breaks before the payload is returned. Structural markers (lists, code fences, tables, headings) are preserved to avoid breaking intentional formatting.Related Issues
