[Copilot]

Exam questions were missing category context and code-tracing prompts were rendered as flattened text in both the active exam view and the post-exam review. This updates the exam presentation path so question metadata and code content are shown in a readable, exam-ready format.

• Question metadata

  • Add a per-question category label to the exam start payload.
  • Render the category as a pill next to the question number in:
    • exam-taking view
    • post-exam breakdown view
  • Use the topic display name as the user-facing category label, with fallback behavior if topic data is unavailable.

• Code block rendering

  • Replace inline escaped question text rendering with structured question content rendering.
  • Parse fenced code blocks and render them as <pre><code> blocks so tracing questions preserve line breaks, indentation, and monospace formatting.
  • Keep non-code prompt text rendered separately from code blocks so mixed prompts display cleanly.

• Review view parity

  • Reuse the same question content renderer in the results breakdown so post-exam review matches the in-exam presentation instead of degrading code prompts into plain text.

• API coverage

  • Extend the exam API test to assert that question category data is returned in the start-exam response.
