Database-agnostic connection used by all platform-neutral CodeGen code.
Display-only connection summary (e.g. host:port/database).
The "owner" user (or the first available user) used for audit fields.
The configured per-platform metadata provider (SQL Server or PostgreSQL).
Bundle returned by CodeGenDatabaseProvider.SetupDataSource that gives the orchestrator everything it needs to begin a CodeGen run: the per-platform metadata provider, a dialect-aware connection, the "owner" user used as the audit principal for generated rows, and a human-readable connection-info string for log output.
