[FR] Add OpenSSF Scorecard Badge for Security Insights

**Is your feature request related to a problem? Please describe.**

I’d like to suggest adding the [OpenSSF Scorecard](https://github.com/ossf/scorecard) badge to this repository’s README to improve transparency around security best practices.

The Scorecard project is an initiative from the Open Source Security Foundation (OpenSSF) that evaluates open-source repositories against a set of automated security checks (e.g., branch protection, dependencies, fuzzing, CI/CD usage, etc.).

**Describe the solution you'd like**

the proposed changes are implemented via 2 steps:
- setting up gitHub workflow with weekly scheduled job
- publishing results as a badge which is available via README

#### Benefits

- Shows commitment to open-source security
- Increases trust with users and contributors
- Automatically updates with your project’s latest Scorecard rating
