Refactor to centralized tokens and new sizing API.

• Centralize all numeric tokens in lib/src/tokens.dart using a library + part structure.
  • lib/src/enums.dart is now the library; tokens.dart is a part with only numbers/constants.
  • Adds icon glyph sizes, visual and target size maps, per-size radii, and motion tokens.
• New enums and names to match spec:
  • M3EIconButtonSize { xs, sm, md, lg, xl }
  • M3EIconButtonWidth { defaultWidth, narrow, wide }
  • M3EIconButtonShapeVariant { round, square }
  • Keep IconButtonM3EVariant (standard, filled, tonal, outlined).
• Behavior updates:
  • Visual vs target sizing: XS/SM enforce 48×48 min target; others match visual.
  • Shape morphing: pressed state uses shared pressed radius; toggle can flip round/square when selected.
• Example app and tests updated to new API.

BREAKING CHANGES:

• Removed IconButtonM3ETokens ThemeExtension; tokens are static in M3EIconButtonTokens.
• Replaced IconButtonM3ESize with M3EIconButtonSize and IconButtonM3EWidth with M3EIconButtonWidth.
• Replaced IconButtonM3EShape with M3EIconButtonShapeVariant.

• Initial release: IconButtonM3E widget (Material 3 Expressive)
• ThemeExtension tokens for size, icon size, radii, and state opacities
• Example app demonstrating variants, sizes, shapes, and toggle
• Basic tests for semantics and hit target size
