refactor: decompose TabBar and Sidebar for reduced complexity
TabBar (8.50 → 9.38):
- Extract useTabDrag hook for drag state management
- Extract computeDropTarget/computeInsertIndex helpers
- Extract TabItem, DropIndicator, TabBarActions sub-components
- TabBar main function reduced from cc=23/176 LoC to ~25 LoC
Sidebar (8.57 → 9.38, SidebarParts 10.0):
- Create SidebarParts.tsx with NavItem, SectionContent, VisibilityPopover
- Extract useSidebarSections hook for section computation
- Extract useEntryCounts hook consolidating 3 useMemos into 1
- Extract useOutsideClick hook (eliminates 3 duplicate useEffect patterns)
- Extract buildCustomizeArgs, computeReorder pure helpers
- Extract CommitButton, ContextMenuOverlay, CustomizeOverlay
- isSelectionActive extracted as pure function (was closure)
- Sidebar reduced from 604 LoC/cc=34 to ~120 LoC/cc=11
