Add automated script to close all open issues and pull requests for repository archival

[Copilot]

This PR addresses the need to close all open issues and pull requests as the repository is being archived. The solution provides both automated and manual approaches to systematically close all 45 open items (28 issues + 17 pull requests) with an appropriate archival message.

What's Added

Automated Script (close_all_issues_and_prs.sh)

• Bash script that uses GitHub CLI to close all open issues and pull requests
• Includes comprehensive error checking and progress reporting
• Automatically adds the specified archival message to each item
• Implements rate limiting delays to avoid API throttling
• Provides clear success/failure feedback for each operation

Comprehensive Documentation (CLOSING_INSTRUCTIONS.md)

• Complete listing of all 45 items that need to be closed
• Manual GitHub CLI commands as a backup option
• Clear execution instructions for different scenarios
• Summary statistics and item numbers for verification

Archival Message

All items will be closed with this message:

"This repo is now being archived, so I'll be closing this out. I'm really grateful you took the time to share and be part of this project <3"

Usage

Simply run ./close_all_issues_and_prs.sh after authenticating with GitHub CLI (gh auth login). The script will handle the rest automatically, providing real-time progress updates as it processes all 45 items.

This solution ensures a respectful and systematic approach to closing all open contributions as the repository transitions to archived status.
