Subject: [PATCH] ci: replace Dockerized shfmt with direct binary install

The mvdan/shfmt:v3 Docker image is not version-pinned and requires a
docker pull on every PR. Install the shfmt binary directly from GitHub
releases instead, matching the version used in .pre-commit-config.yaml
(v3.13.1). Avoids a container pull while keeping behaviour identical.
