The hand-rolled pre-commit.sh reimplemented what upstream hooks already do.
Move to pre-commit.com with the estate's usual pre-commit-hooks set plus
hadolint and shellcheck, and keep the one check with no upstream equivalent
(distros/ vs the Woodpecker matrices) as a repo: local hook.
The test harness goes; tests will be reintroduced differently.
- add .pre-commit-config.yaml and ci/check-distros.sh
- delete pre-commit.sh, test.sh and .woodpecker/test.yaml
- run uvx pre-commit run --all-files from .woodpecker/pre-commit.yaml and make pre-commit
- drop the Dockerfile test stage and the make test targets
