Code Review

This pull request adds actionlint as a pre-commit hook to lint GitHub Actions workflows. My review suggests an improvement to enhance the security and reproducibility of this new hook by pinning it to a specific commit SHA instead of a tag, which is a best practice for pre-commit configurations.

[gemini-code-assist]

For security and reproducibility, it is a best practice to pin pre-commit hooks to a specific commit SHA rather than a tag. Tags are mutable and can be moved, which could result in running unexpected or malicious code. The SHA for tag v1.7.11 is 19e43c05f884b6c134de652293b5224326884f16.
