Code Review

This pull request updates the allowed range for the transformers dependency up to 5.13.0 and modifies the license checking script to support a range of valid years (2023-2026). The feedback recommends aligning the runtime dependency check with the exclusions specified in pyproject.toml to avoid known broken versions, and improving the license check logic to robustly handle files that begin with shebang lines.
