Problem

The citation section in README.md contains a DOI link that is not formatted as a proper absolute HTTPS URL.

Currently the link appears as a relative/plain DOI string instead of a fully qualified clickable URL. This may cause issues with link detection in browsers and academic tools.

Expected behavior

The DOI citation link should use a proper HTTPS format:

https://doi.org/

so that it is clickable and standards-compliant.

Proposed fix

Update the DOI citation line in README.md to use a full HTTPS DOI link.

This is a documentation-only change and does not affect code behavior.

Why this matters

• Improves documentation quality
• Ensures citation links are clickable
• Matches standard academic DOI formatting
• Helps users properly reference the project

I’d be happy to submit a PR to fix this.
