feat!: Friendlier typing for the ActiveState.aria property

[webJose]

Closes #106.

[Copilot]

Pull Request Overview

This PR improves the developer experience by simplifying the syntax for ARIA attributes in the ActiveState.aria property. Instead of requiring the full aria-* prefix (e.g., 'aria-selected'), developers can now use the unprefixed attribute name (e.g., selected).

• Introduced a new ActiveStateAriaAttributes type that maps unprefixed ARIA attribute names to their values
• Updated activeBehavior to prepend aria- when setting/removing attributes
• Updated Link.svelte to transform unprefixed ARIA attributes to prefixed ones before applying them to the anchor element
