// Gate: falha se o git rastreia artefatos de build/artefatos gerados proibidos.
// Guarda contra `git add -A` acidental em worktrees que include node_modules symlinks.
// Incidente registrado 2× neste repo (v3.8.12 / v3.8.13) — Hard Rule #7 extensão.
//
// Artefatos proibidos:
//   - node_modules/  — deps de build nunca devem entrar no repo
//   - .next/         — output do build Next.js
//   - coverage/      — relatórios de cobertura gerados pelo c8
//   - quality-metrics.json — saída do collect-metrics.mjs (gerado, não-versionado)
//   - symlinks rastreados (mode 120000) — indício de `git add -A` em worktree
