lgcosta 11fc26390d feat(autosave): grava por ociosidade (10s padrão, configurável) e em silêncio
- debounce de 1,5s → 10s SEM nenhuma alteração (cada tecla reinicia);
  seletor 5/10/30/60s no diálogo de Preferências (autosaveDelay, clamp 5–120)
- autosave silencioso: sem toast, só o status 'salvando…/salvo'; Ctrl+S
  manual mantém o toast com o hash da revisão
- flush de pendências ao trocar de aba do app e em visibilitychange=hidden
  /pagehide (melhor esforço) — nada se perde ao sair antes do idle
- README atualizado
