Fix execution trace panel collapse/expand functionality

- Expose toggleTracePanel() to global scope for onclick access
- Add localStorage state persistence for collapsed/expanded state
- Add restoreTracePanelState() to remember user preference
- Update onclick handler to safely call global function
- Bump cache-bust version to force browser reload

The trace panel toggle button now works correctly and remembers
its state across page reloads.
