- GeradoresService: cada tipo passa a ser um IGenerator (NIF, NIPC, NISS, CC, passaporte, IBAN, NIB, cartões, referência MB, pessoa, telefone, código postal, email, matrícula, EAN, UUID) registado em GeneratorRegistry; remove DAL/EF - GeradoresWS: minimal APIs em /api/v1 com OpenAPI + Scalar e health check - UnitTest: testes de ida e volta, valores conhecidos, detecção e API - geradoresfe: UI construída a partir dos metadados da API, validador livre, exportação CSV/JSON/TXT, nginx com API_UPSTREAM configurável - Docker, docker-compose e Jenkinsfile actualizados Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
