[GOOD FIRST ISSUE]: Improve GitHub API caching for Org Explorer

[PunyaGowdagd66]

Context

The current implementation repeatedly calls GitHub APIs which may cause rate limit issues.

This issue proposes implementing a caching strategy using TTL-based caching and local storage to reduce redundant API calls.

What Needs to Be Done

• Analyze the current GitHub API request flow in the project
• Implement a TTL-based caching mechanism to reduce repeated API calls
• Store cached repository data using IndexedDB
• Add a manual refresh button to allow users to refresh cached data
• Ensure API requests respect GitHub rate limits

This issue was created to propose improvements to the GitHub API caching system.

It is not related to PR #26 (Tailwind migration).
That mention happened automatically.

I will open a separate PR for this feature in the future.
