Stop script/lint writing an image it never uses (closes #48)

script/lint builds Dockerfile.lint only for the exit status, but every run exported the result as an image: seconds spent exporting, and one untagged image left behind each time. It now builds with --output=type=cacheonly, so nothing is exported. CHECK_EPOCH still changes on every run, so the gate steps still run each time; the build cache is kept as before. Model: opus-5-5
