chore: add ruff format hook to pre-commit config

[chalmerlowe]

The Problem

The repository pre-commit configuration only ran ruff-check for sorting and fixing imports (--select I --fix). It did not run ruff format on staged files. As a result, commits could pass local pre-commit checks but subsequently fail repository lint sessions during presubmit testing due to formatting discrepancies.

The Solution

• Added the ruff-format hook to .pre-commit-config.yaml
• Configured arguments --target-version=py310 and --line-length=88 to align with the formatting standards enforced across the repository's lint Nox sessions.

Notes to Reviewers

• This change ensures that code formatting is automatically applied locally prior to commit, matching what our CI/CD lint sessions expect.

Code Review

This pull request updates the .pre-commit-config.yaml file to include the ruff-format hook, ensuring that code formatting is automatically applied alongside the linter. There are no review comments, and I have no feedback to provide.
