0.1.0

Initial public release.

Added

• LiquidGlassBottomNav — a premium floating Liquid Glass bottom navigation bar with a real BackdropFilter blur clipped to the bar only.
• Tap navigation — onTap fires immediately on tap with a selection haptic.
• Smooth drag preview — the liquid capsule follows the finger continuously; the page does not change during the drag.
• Commit on release — navigation commits exactly once, on release, for the nearest tab (dragging across tabs never opens intermediate screens).
• Organic liquid bubble/drop indicator — a tapered-superellipse "lens" shape (never a rectangle, pill, oval or circle) with gradient, reflection, rim-light border, glow and depth shadow.
• Balanced top/bottom overflow — the bubble bulges equally over both edges of the bar while dragging, painted into reserved headroom so it is never clipped and never reaches the safe area.
• Horizontal liquid stretch — the drop widens into a centre-anchored horizontal capsule and elongates toward a flick.
• Menu magnification (liquid lens) — items magnify based on distance from the bubble centre (the icon leads the label).
• Filled active icons — the selected tab, and the tab under the bubble during a drag, show their filled selectedIcon.
• Light and dark mode — colours auto-resolve from the ambient theme.
• LiquidGlassNavItem — destination model (icon, optional selectedIcon, label, optional semanticLabel, optional badgeCount).
• LiquidGlassNavTheme — full visual/behaviour configuration with sensible defaults.
• SafeArea support, max-width centring, reduce-motion support and a RepaintBoundary-isolated, self-halting drag-physics ticker for good performance.
• A runnable example app with five tabs and an IndexedStack.
