Description

In PR #136, #144, and #149, there were issues with CI not passing.

Ruff updated its format rules in version 0.9.0.

The CI didn't specify the Ruff version, which caused it to download the latest version.
However, the version in uv.lock is fixed at 0.8.6, leading to differences between local Ruff format execution and the CI results.

I tried many times to fix it and wasn't sure why it failed in CI
Thank you!
