Code Review

This pull request updates the psf/black pre-commit hook from version 25.9.0 to 25.12.0. While this is a good maintenance task, it's important to ensure that the version of black used in the pre-commit hook is consistent with the version used in the development environment. Currently, the pyproject.toml specifies black = "^25.0.0", which has resolved to 25.11.0 in poetry.lock. This discrepancy can lead to inconsistent formatting and CI failures. I've added a comment to suggest aligning these versions.

[gemini-code-assist]

This update to version 25.12.0 is good, but it creates a version mismatch with the black dependency in your development environment. Your pyproject.toml specifies black = "^25.0.0", which is currently locked to 25.11.0 in poetry.lock. To ensure consistent formatting between local runs and pre-commit hooks, it's best practice to align these versions. Please consider updating the black dependency in pyproject.toml to ^25.12.0 and regenerating the lock file.
