Azure SQL Developer in CI

Run integration tests against the Azure SQL Database engine (Private Preview) as a CI service container. This is the local Azure SQL engine, not the SQL Server image mcr.microsoft.com/mssql/server. SELECT SERVERPROPERTY('EngineEdition') returns 5 and SERVERPROPERTY('Edition') returns 'SQL Azure'. If a workflow was about to use the SQL Server image, stop and use this image instead.

For full container detail (readiness loop, connection model, vectors, seeding), see the azuresql-db-container skill and its wait-until-ready.md and image-and-registry.md.
