- Renders tabs from useFileStore.openTabs with title + dirty dot + close button
- Uses Zustand selectors for granular re-renders
- Active tab highlighted with aria-current and accent background
- Close button stops propagation; does not trigger tab activation
- Horizontal scroll on overflow, h-9 fixed bar with border
- Empty state preserved when no tabs open
Tests: 6 cases (empty, render, highlight, click-switch, click-close, dirty indicator)
- 75 total tests (was 70, gained 5 new)
- All pass
- Build: succeeds
