## 🛠️ Top 3 Actionable Fixes
1. **Fix settings menu crash** caused by unvalidated API credentials in LM Studio configuration blocks.
2. **Implement dynamic database seeding** in CLI diagnostic flows to provide local telemetry context.
3. **Audit and reduce dashboard sidebar width** on compact viewports to prevent layout wrapping.
