Create a detailed Pull Request template

[AlAfiz]

Description

To ensure reviewers have all the necessary context, we need a standardized template that auto-populates whenever a developer opens a Pull Request.

Acceptance Criteria

• Create a .github/pull_request_template.md file.
• Include a "Description" section linking back to the original Issue.
• Include a "Type of Change" checklist (Bug fix, New feature, Breaking change).
• Include a "Testing Strategy" section where the author explains how they verified the code.
• Include a checklist for self-review (e.g., "I have run the linter," "I have updated the docs").

Technical Details

• Keep the template concise so it doesn't become a bureaucratic burden.
