- rails 7.2 → 8.1, ruby 3.2, sqlite3 2.x
- adiciona primary_key Idinformativo no model
- schema.rb completo com todas as tabelas
- testes minitest: models (Tag, Informativo, Tema) e controllers
- readme atualizado em pt-br com stack e instruções de desenvolvimento
- gitignore exclui dump.sql, *.duckdb e sqlite3
