Run the repository-managed pre-commit installation directly so CI no longer expands the wrapper's actions/cache@v4 dependency, which violates the full-SHA action policy. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 08f0eec5-45eb-485a-b89d-d0de33568add

Why
The repository now requires every external GitHub Action to be pinned to a full commit SHA. Although
pre-commit/actionitself was pinned, its composite action invokesactions/cache@v4by a mutable tag, causing both CI lint jobs to fail during workflow preparation.Run the already-installed repository dependency directly instead of using the wrapper. This preserves the same pre-commit arguments and GitHub annotation behavior without introducing a transitive unpinned action.
