yhirose f83d06538b Track Homebrew's clang-format version instead of a fixed pin ...

The previous commit pinned CI and the pre-commit hook to a fixed
clang-format 23.1.0, but the maintainer develops on macOS against
whatever version `brew` currently installs, which changes over time
as Homebrew updates the formula.

style-check now runs on macos-latest and installs clang-format via
`brew install`, so it tracks the same moving target the maintainer's
Mac does. The pre-commit hook switches from pre-commit's own pinned
mirror to a local hook that shells out to the system clang-format,
so a local commit and CI both go through the same Homebrew-installed
binary rather than two independently versioned copies.

Trade-off: this reintroduces the non-determinism a fixed pin avoids
-- a commit's style-check result can now change over time as Homebrew
updates the formula -- but that mirrors how the maintainer already
develops, which is the point.

Also install coreutils in CI: the style_check Makefile target needs
grealpath's --relative-to, which the macOS-native realpath lacks.
