# Git Pre-Commit Hook: Unit Test Enforcement
#
# This hook runs all unit tests before allowing a commit.
# It enforces the 100% unit test passing requirement.
#
# Installation:
#   cp .git-hooks/pre-commit .git/hooks/pre-commit
#   chmod +x .git/hooks/pre-commit
#
# Bypass (use sparingly, WIP commits only):
#   git commit --no-verify
