feat: Add automation to manage stale issues and PRs #1009

🚀 The feature

Description:

Currently, the repository does not have any automated mechanism to manage inactive (stale) issues and pull requests. As a result, many old issues and PRs remain open indefinitely, even when they are no longer relevant or actively being worked on. This leads to:

• Cluttered issue tracker
• Increased maintenance overhead
• Difficulty in identifying active vs inactive work
• Slower triaging process for maintainers

To improve repository hygiene and reduce manual effort, we propose adding an automated Stale Issue Bot using GitHub Actions.

Proposed Solution:

We propose implementing a Stale Issue Bot using the actions/stale GitHub Action. The bot will automatically monitor issues and pull requests and take the following actions:

✅ Behavior of the bot

1. If an issue or PR has been inactive for 60 days:
   • The bot will post a comment notifying that it has become stale.
   • The bot will add a stale label to the issue/PR.
2. If there is no activity for 7 more days after marking it stale:
   • The bot will automatically close the issue or PR.

Proposed Implementation :
A new workflow file should be added:

.github/workflows/stale-bot.yml

Expected Benefits:

This automation will:

• Keep the repository clean and organized
• Reduce manual effort for maintainers
• Help prioritize active issues and PRs
• Prevent outdated discussions from lingering indefinitely
