Type of Change

• Bug fix
• Accessibility improvement
• New feature
• Documentation update

Changes Made

• Updated the inner progress <div> in src/components/GoalTracker.tsx with role="progressbar".

• Added a descriptive aria-label formatted as [Goal Title]: [Current] of [Target] [Unit].

How to Test

1. Open the DevTrack dashboard locally with at least one active goal.
2. Run an accessibility audit using browser DevTools or Axe.
3. Verify that the progress bar now exposes the correct roles and ARIA values.
4. If using a screen reader (like VoiceOver or NVDA), navigate to the progress bar and confirm it accurately announces the goal's title and its current progress values.

Thanks for the suggestion! Even though pct is clamped during initialization, I have added explicit [0, 100] bounds clamping directly to aria-valuenow as requested to guarantee it remains consistent with the rendered progress width and safe for assistive technologies.
