// 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
//   - _tasks (exato E prefixo) — repo git SEPARADO; o blob symlink rastreado causou DOIS
//     wipes do diretório real (2026-08-08 e 2026-08-10; Hard Rule #23)
//   - _references/ _mono_repo/ _ideia/ _cache/ — diretórios privados de raiz (regra /_*/)
//   - .claude/worktrees/ — worktrees de sessão nunca entram no repo
//   - docs/superpowers/ — artefatos de planejamento vivem em _tasks/, não em docs/
//   - .eslintcache* .fakebin-* dist/ .build/ .artifacts/ logs/ — caches e outputs gerados
//
// Todos os prefixos são ancorados na raiz (startsWith sobre paths do `git ls-files`):
// paths aninhados legítimos como `src/lib/logs/` NÃO são atingidos.
