Improve Stability, Security, and Maintainability

This pull request focuses on addressing key vulnerabilities, bug fixes, and code maintainability improvements without extensive restructuring, ensuring easy review and integration.

Main improvements:

Security and Dependency Improvements

• Eliminated vulnerable dependencies:
  • Replaced deprecated and vulnerable request-promise-native and node-fetch with secure, actively maintained axios.
  • Resolved vulnerabilities identified in Gemfile.lock.

Critical Bug Fixes

• Fixed incorrect state comparisons causing unnecessary repeated state notifications every 15 minutes.
• Resolved module resolution issues related to ES Modules and fixed __dirname undefined errors.

Data Management Enhancements

• Removed duplicated and redundant data storage in Gist updates, improving data efficiency and accuracy.

Code Quality & Maintainability

• Introduced ESLint configuration (eslint.config.mjs) to enforce consistent coding practices.
• Formatted source code uniformly across the project for better readability and consistency.
• Simplified environment variable management by adding environment shortcuts (env.js).

Documentation Improvements

• Corrected typos and improved clarity in multiple README files.

CI/CD Pipeline Updates

• Updated Node.js version in GitHub Actions workflows to enhance performance and compatibility.

Verification

• All changes are tested thoroughly locally and validated through CI/CD pipelines.
• Ensured no regressions or side effects were introduced.

This PR isolates the most critical improvements and addresses feedback from the previous PR by limiting the scope for a clearer and quicker review process.
