Comprehensive Scope & Optimizations for Statistics & Heatmap

[hugomarins]

Summary

This PR significantly enhances the "Current Rem" context functionality in both the Statistics and Heatmap widgets. It introduces a "Comprehensive" scope option that gathers data not just from descendants, but also from related contexts (portals, references, sources, table views). Additionally, it implements a performance optimization to handle large datasets efficiently and adds UI improvements.

Key Changes

1. New "Comprehensive" Scope Logic

• Created a shared helper function getComprehensiveContextRems (in src/lib/utils.ts) that gathers a broader context for a specific Rem, including:

  • Direct Descendants
  • Rems in the same Document/Portal context
  • Folder Queue Rems
  • Sources
  • Referencing Rems (Backlinks)
  • Table Views inside the document

• UI Update: Added a radio button selector in the sidebar (visible only when "Current Rem" is selected) allowing users to toggle between:

  • Descendants Only: (Default) Traditional behavior, faster.
  • Comprehensive: Uses the new logic to show a holistic view of the Rem's ecosystem.

2. UI/UX Improvements

• Total Flashcards Count: Added the total number of cards in the currently selected scope.
• Retention Rate Tooltip: Added an information icon next to the Retention Rate label with a tooltip explaining the formula used ((Hard + Good + Easy) / Total Reviews).

3. Code Organization

• Moved shared logic to src/lib/utils.ts.
