Community-maintained driver for Devart UniDAC integration with the Dext ORM framework.

[IMPORTANT] Maintenance & License Notice: The maintainers of the Dext core repository do not hold a commercial license for Devart UniDAC. Consequently:

• Automated CI tests and core builds do not include UniDAC components.
• Maintenance, support, and compatibility updates for this driver are entirely provided by the community members who use UniDAC.

Architecture Roadmap Note: To better accommodate community database drivers (such as UniDAC) without modifying core setup units, Dext.Entity.Setup.pas is planned for refactoring to support dependency injection and pluggable driver factories (IDbDriverFactory).

For details on the planned refactoring, see Specification S56: Driver Abstraction & Setup Refactoring.

This driver provides full integration between Dext ORM (IDbConnection, IDbCommand, IDbReader, IDbTransaction) and Devart UniDAC components (TUniConnection, TUniQuery, TParam), enabling seamless usage of UniDAC database providers (SQLite, PostgreSQL, MySQL, SQL Server, Oracle, InterBase/Firebird, etc.) without introducing compile-time third-party dependencies into the core framework.

1. Add Community/Drivers/UniDAC/Sources to your project's search path.
2. Include Dext.Entity.Setup.UniDAC and Dext.Entity.Drivers.UniDAC in your unit's uses clause.
3. Build your connection using the standalone helper:

   var
     Options: TUniDACDbContextOptions;
     Conn: IDbConnection;
   begin
     Options := TUniDACDbContextOptions.Create;
     Options.UseSQLite(':memory:');
     Conn := Options.BuildConnection;
   end;
