Adds native schema introspection (information_schema, no Java/SchemaCrawler required) and query execution (psycopg2/pymysql) for PostgreSQL and MySQL, routed via a new db_dialeto/db_config state field. The code-gen prompt now tells the LLM which dialect it's targeting instead of always assuming SQLite. SQLite behavior is unchanged (dialect defaults to sqlite when not specified).
Adds an optional db_url field (e.g. postgresql://user:pass@host:port/db) that, when set, drives schema introspection and query execution through SQLAlchemy instead of the manual db_dialeto/db_config path added earlier. The dialect is read from engine.dialect.name, so the caller only needs to provide one connection string instead of six separate flags/params. This is purely additive: when db_url is not set, behavior is unchanged (same db_dialeto/db_config/db_path path as before).

Adicionei suporte a PostgreSQL e MySQL. Criei a introspecção de schema pros dois bancos (via information_schema, sem precisar de Java/SchemaCrawler) e os executores de query (psycopg2 e pymysql), com a mesma validação de segurança de antes (só SELECT/WITH). O prompt do LLM agora sabe qual banco é o alvo, em vez de sempre assumir SQLite (Isso estava me dando problema). Testei tudo local com Postgres 17 e MySQL 8.4, incluindo uma query de exemplo do BIRD que vcfs passaram, e rodei a suíte de testes inteira para ver se quebrava algo do SQLite, e deu tudo certinho. Fiz um docx detalhando mais o processo
