Description

This PR resolves #440 by eliminating UI freezing and latency during Firestore round-trips. By implementing an Optimistic UI pattern, critical user interactions now reflect state changes instantly, greatly enhancing the perceived performance of the application.

Key Additions & State Rollbacks

  • Social Follow (DeveloperCard.jsx): Users can now toggle follow/unfollow states instantly. If the backend transaction fails (e.g., due to network drop), the component gracefully rolls back to its previous state.
  • Gamification (Achievements.jsx): Badge and Daily Quest XP claims now process optimistically. The UI instantly updates the progress and hides the claim button without waiting for the database confirmation.
  • Shop & Streaks (CodingOwl.jsx): Integrated optimistic updates across multiple complex interactions:
    • Pomodoro Session: Timer completion instantly awards HubCoins.
    • Habit Checklist: Checking off a daily habit instantly updates the UI to 'Completed'.
    • Mascot Shop: Purchasing and equipping mascots deducts coins and updates the active mascot instantly, rolling back inventory and coin balance seamlessly if the purchase fails.

Fixes #440
