#!/usr/bin/env bash
# One-time installer for the local pre-commit gitleaks hook.
# Run once per clone: bash scripts/git-hooks/install.sh
#
# Respects `core.hooksPath` if you've set one (local or global) — some setups
# point git at a hooks dir outside `.git/hooks/` (e.g. a machine-wide
# `~/.git-hooks/`), and installing to `.git/hooks/` in that case would be a
# silent no-op. If an existing hook is already at that path, this chains to
# it so nothing already relying on it breaks.
