⚡ Performance (Breaking)

• Custom RenderObject: Replaced Flutter's native IndexedStack with a custom _RenderLazyStack that skips layout computation entirely for inactive children. Only the active child participates in layout/paint.
• Cached Animations: All CurvedAnimation and Tween objects are now created once per transition and cached as state fields — zero per-frame allocations.
• Optimized loadedIndexes: Returns Set<int>.unmodifiable() instead of allocating a new Set on every access.
• Eliminated double eviction: switchTo no longer calls _enforceMaxSize twice.
• Removed dart:math dependency: Inlined max comparisons.

✨ Features

• Native Tab Animations: Added IndexdAnimationType enum with 5 transition styles:
  • none (zero-overhead, no AnimationController allocated)
  • fade
  • fadeThrough (Material Design spec)
  • sharedAxisHorizontal
  • sharedAxisVertical
• Dynamic Animation Toggling: Switching between none and animated types at runtime is fully supported with proper resource lifecycle management.
• Nullable AnimationController: When animation: IndexdAnimationType.none, no AnimationController is created — true zero allocation.

🔧 Breaking Changes

• Removed EQ prefix: EQLazyStackController → LazyStackController, EQLazyLoadIndexedStack → LazyLoadIndexedStack.
• Removed removableIndexes: Dead field that was never used internally.
• Changed base class: LazyLoadIndexedStack is now a StatefulWidget (was ListenableBuilder).
• Removed StackFit sizing parameter: The custom RenderObject handles sizing internally.

🐛 Fixes

• Controller now uses ChangeNotifier instead of manual listener management.
• switchTo performs synchronous eviction before notifyListeners() — no double-frame builds.
• Memory pressure handler (didHaveMemoryPressure) aggressively flushes all inactive pages.
