guardian-db 0.19.0

// Testes abrangentes para o módulo core do GuardianDB
//
// Este módulo testa as funcionalidades principais do GuardianDB:
// - Inicialização e configuração
// - Gerenciamento de stores
// - Verificação criptográfica de identidades
// - Sincronização de heads
// - Sistema de eventos (Emitters)
// - Lifecycle management (close, cleanup)
