DataAgent 0.7.4

Fix recursive settings arrays introducing PSObject wrappers that compiled cmdlets such as Invoke-Sqlcmd reject. Native foreach now preserves actual CLR element types. No SQL-specific cast, adapter change or cleanup change.

Native Type.GetTypeArray regression is red on the old pipeline and green on the repair.113 acceptance checks, CLR string/mixed/null/list/nested/env/credential cases, package checks and real SQL validation against closed loopback port1 pass. Windows, Linux and macOS CI passed the exact reviewed head.

Clear-Files remains pinned to1.1.0.0. No automatic caller migration or fleet installation.
