feat: add stack frame navigation to error overlay
- Add click/keyboard support to select stack frames in the call stack
- Show codeframe for any selectable stack frame (not just the first one)
- Codeframe visibility based on ignore list state: only show codeframe
for visible frames (hidden when ignore list is collapsed)
- Improve ignore list detection for monorepo workspace paths
- Ignore frames with no useful source location (likely internal framework code)
- Use accessible faux nested interactive controls pattern
- Add tests for frame selection behavior
