chore(badge): refactor with abstracted base class

[TarunAdobe]

Overview

This PR refactors the sp-badge component to separate its base logic from rendering code, following the technical specifications for the Swan migration preparation. This is a purely internal change with no customer impact.

Changes Made

File Structure Changes

• Created: New packages/badge/src/Badge.base.ts as the base class for Badge component.

Code Separation

BadgeBase (Abstract Base Class)

• Location: packages/badge/src/Badge.base.ts
• Contains:
  • Property declarations
  • All base functionality except rendering

Badge (Concrete Class)

• Location: packages/badge/src/Badge.ts
• Contains:
  • Class that extends BadgeBase
  • Rendering logic (render() method)
  • Styles import and declaration

Impact

Customer Impact

• None - This is a purely internal refactoring
• Public API remains identical
• No visual or behavioural changes
• No breaking changes

Developer Impact

• None - Existing imports and usage patterns continue to work
• import { Badge } from '@spectrum-web-components/badge' still works
• All existing component usage remains valid

Manual review test cases

• Manual Testing

  • Component renders correctly in Storybook
  • All variants (horizontal/vertical) work as expected
  • All sizes (s, m, l) display properly
  • ARIA attributes are set correctly

• Automated Testing

  • All existing tests pass
  • No new tests needed (no functional changes)

Device review

• Did it pass in Desktop?

• Did it pass in (emulated) iPad?

Migration Preparation

This refactoring prepares the badge component for future migration to the Swan architecture by:

1. Separating concerns - Base logic vs. rendering logic
2. Preserving git history - Base logic in Badge.base.ts will carry forward
3. Maintaining compatibility - Public API unchanged
4. Following established patterns - Consistent with other component refactoring

Nice work, including the PR description (which I totally copied for my component btw). Left two suggestion that will fix your tests, if you commit them.

We don't need to add this now as this would change the existing API contract.

[blunteshwar]

Shouldn't we add export * from './Badge.base.js'; in index.ts file as well so that we could use/import objects exported by BadgeBase in stories and tests.
