feature: Add structured GitHub Issue Templates

[aniruddhaadak80]

Motivation

The repository currently lacks structured templates for issues. This makes it difficult for maintainers to efficiently reproduce bugs or understand the context behind feature requests because users might omit critical details.

Proposal

Add .github/ISSUE_TEMPLATE/bug_report.yml\ and .github/ISSUE_TEMPLATE/feature_request.yml\ to enforce structured forms for:

• Bug Reports: Requiring OS, Python version, steps to reproduce, and expected behavior.
• Feature Requests: Requiring motivation, proposed solutions, and alternatives.

This complements the newly added PR template and greatly reduces back-and-forth communication.

Hi maintainers 👋

I noticed you’re already working on issue #368. I had also prepared bug report and feature request templates in my fork. If it’s helpful, I’d be happy to update my PR to match your standards — for example, renaming the files to .yml and adding required: true validations on key fields.

Please let me know if you’d like me to reopen and adjust my PR, or if you prefer to continue with the existing work. Either way, I’m glad to contribute and support the project.
