fix: Study Progress Does Not Update Immediately After Completing Tasks (#435)

[Parmarprashant]

This PR resolves issue #435 where the study progress tracker and completion statistics failed to update instantly when a task was marked as completed. Users previously had to refresh or navigate away to see their updated progress.

Changes

• Reactive UI Updates : Subscribed the renderSummary function to the central store in app.js . This ensures that any change in task status (Done/Pending) triggers an immediate re-render of the summary statistics.
• Visual Progress Bar : Added a dynamic progress bar and percentage indicator to the Summary Box for better visual feedback.
• Accurate Badge Counting : Refined the sidebar badge logic to count only pending tasks, aligning with the "All Tasks" display and improving productivity tracking accuracy.
• Accessibility Improvements : Updated aria-label attributes on badges to dynamically reflect the number of remaining tasks.

Verification

• Marking a task as "Done" instantly updates the "Overall Progress" bar and percentage.
• Daily and Weekly task counts in the summary panel update immediately.
• Sidebar badges correctly decrement upon task completion without page refresh.
