this PR addresses #707 and adjusts how our validation scripts behave during pre-commit checks.

Summary

at the moment, scripts like check-image-names.py, check.sh, and check-size.sh also pick up untracked local files. This can cause pre-commit to fail even when those files aren't part of the repository.

With this change, the scripts now only operate on files that are actually tracked by Git. Untracked local files are ignored.

Changes

• check-image-names.py now determines tracked files using git ls-files and skips anything untracked.
• check.sh and check-size.sh have been updated to validate only Git-tracked files.

This keeps the naming and size checks strict for repository content, while avoiding unnecessary failures caused by local development files.

Impact

• pre-commit no longer fails because of untracked local files.
• Naming and size rules are still enforced for all tracked content.
• The workflow becomes less frustrating for contributors without reducing repository standards.

Checklist
