A completely absent `prettier` binary went unnoticed long enough for unformatted markdown to reach main. Two independent causes, both fixed here. No pre-push hook existed. The three hooks declaring `stages: [pre-push]` in .pre-commit-config.yaml — prettier, ci-mirror, pytest-coverage — therefore never ran locally at all. Adds one. The pre-commit hook failed open. shfmt and shellcheck were wrapped in `if command -v`, and the entire pre-commit framework was skipped with a warning when its binary was missing. A silently skipped gate is indistinguishable from a passing one, so a missing tool now aborts. - lib/common.sh: require_tool tries `sudo -n pacman -S` and aborts with the exact command when a tool cannot be installed non-interactively; verify_toolchain applies it to all eight binaries the hooks invoke. - The pre-push hook resolves git's stdin refs into --from-ref/--to-ref. Without a range, `pre-commit run --hook-stage pre-push` checks *staged* files, and nothing is staged at push time, so prettier would have received zero files and passed vacuously. - ensure_hooks_path repairs core.hooksPath drift on every hook run. - meta/scripts/install_hooks.sh covers the one case the hooks cannot self-heal — a fresh clone where the config was never set, so nothing runs. `--check` reports state and exits non-zero when incomplete. Note `pre-commit install` must never be used here: it writes into .git/hooks/, which git ignores entirely while core.hooksPath is set.
