Performance: Browser becomes unresponsive with very large answers (5,000 lines)

Question

**Type:** enhancement  
**Summary**  
Large outputs (e.g., DIFF/LOG) freeze the browser.

**Proposal**  
Provide a setting to **collapse DIFF/LOG by default** and lazy-load large sections to avoid memory spikes.

**Expected**  
UI stays responsive, with expandable sections for heavy content.
