[ci-scan] Build break: -cdacPath requires the matching universal DBI in runtime-diagnostics cDAC leg #133301

Build Information

Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1582309
Build error leg or test failing: runtime-diagnostics (definition 309) — cDAC_windows_x64_release leg, eng/build.ps1 cDAC validation step.

Pipeline: runtime-diagnostics (definition 309), branch main. The SOS/cDAC test leg builds with -dacMode cdac -cdacPath .../artifacts/cdac/mscordaccore_universal.dll, then build.ps1 fails its own precondition check: it requires the matching universal DBI (mscordbi_universal.dll) to be present alongside the cDAC path, aborts with a WriteErrorException, and Cmd.exe exits code 1 before any test runs. This is a build/infra break, not a test failure — the leg never produces test results. Reproduces across source build 1582309 and follow-up build 1584156.
