🚀 Major Enhancement: Refactored into a Professional GitHub CLI Tool

[MRThugh]

Overview

This PR provides a significant upgrade to the existing script, transforming it from a basic helper into a robust, production-ready CLI tool.

Major Improvements:

1. Security: Migrated away from passing tokens as arguments. Added support for environment variables, .env files, and secure prompts to prevent token leaks in shell history.
2. Data Integrity: Replaced manual array appending with jq flattening. The script now ensures the output is always a single, valid JSON array.
3. Reliability: Integrated set -euo pipefail and trap for automated cleanup of temporary files.
4. UX/UI: Added colorized logs (INFO/WARN/ERROR), a progress spinner for long fetches, and a comprehensive --help menu.
5. API Intelligence: Added a Rate Limit checker that warns the user when API quotas are low.
6. Versatility: Added full support for various HTTP methods (POST, DELETE, etc.) and custom data payloads.

Testing

• Verified pagination with large repositories.
• Tested token security across different environments.
• Validated JSON output with external linters.

I believe these changes will make this tool much more useful and safer for the community. Looking forward to your feedback!
