refactor: Refactor Code with clippy Without Any Logical Change

🛠️ Refactor Code with Clippy (No Logic Change)

This pull request refactors the codebase by applying suggestions from clippy, Rust’s built-in linter. The changes aim to improve code readability, consistency, and style without introducing any functional or behavioral modifications.

✅ Summary of Changes:

• Simplified nested if let and match statements (e.g., collapsible matches)
• Removed redundant clones and bindings
• Applied idiomatic Rust patterns where safe and clear
• Ensured all changes pass existing tests and preserve original logic

This is a non-functional cleanup PR, safe for review and merge without risk of regression.

Thanks for the contribution, @Cierra-Runis!

Would you mind throwing a license file in here while you're at it, as you suggested?

I'd also suggest updating the CI workflow to include a clippy check, to ensure that this standard will be maintained.

I'd love to❤️. However, it's best if each pull request addresses only one issue or feature for clarity and easier review. Next Pull Request is coming😘.
