pre-commit

#!/usr/bin/env bash
#
# Git pre-commit hook that runs all CI checks
# This hook dynamically reads the GitHub Actions workflow file and executes
# the same lint and test commands that run in CI.
#
# This hook is installed automatically by the Claude Code session-start hook
# IMPORTANT: These checks mirror CI - if they fail here, the PR will fail CI.
# Always fix the issues rather than bypassing this hook.
