Summary

Adds the ProgressBar component (feedback category) and the theme animation tokens it depends on.

• webkit — new progress-bar component published under the flat export @aziontech/webkit/progress-bar, with its spec (.specs/progress-bar.md) and a Storybook story under Components/Feedback/ProgressBar.
• theme — new progress-indeterminate / progress-indeterminate-short semantic animation utilities, backed by new slow-03 (1100ms) / slow-04 (2100ms) duration primitives and progressIndeterminate* keyframes. Regenerated dist/v3 + dist/v4 globals.

Indeterminate animation uses logical properties (inset-inline-*) so it's RTL-aware, and pairs with motion-reduce per the styling rules.

Notes

• Version impact: minor bump for both @aziontech/theme and @aziontech/webkit.
• No new external dependencies (CSS + tokens only, per dependencies.md).
• No breaking changes.
• Relates to ENG-46485.
