Skip CI when no code changes (like .rs or .toml file changes) are made...

[KushalMeghani1644]

I have noticed that currently even if a README or LICENSE change is made the entire CI runs once again for checks that won't be affected anyway this wastes CI minutes.

My idea is that: GitHub Actions supports path-based filtering, which can be used to skip CI runs when no files affecting compilation (e.g. .rs, Cargo.toml) are changed.

This could:

• Reduce unnecessary CI runs
• Save CI minutes
• Shorten feedback time for docs-only PRs

If this is something you'd consider, I’d be happy to follow up with a minimal PR using path filters.

Thanks for your time!
