GlassEffect class

Enhanced glass renderer specifically for interactive indicators.

Uses a specialized shader on Skia/Web to match Impeller's visual quality with magnification effects, enhanced rim lighting, and radial brightness.

On Impeller with premium quality, it uses the native LiquidGlass renderer. On Skia/Web or standard quality, it uses the enhanced GlassEffect shader with magnification and structural rim effects.
