Replace dotnet run with dotnet exec to bypass SDK argument parsing regression

dotnet run in SDK 10.0.300 incorrectly forwards its own options
(--verbosity, --configuration, --no-build) as application arguments
on the CI agent (Ubuntu 22.04). This cannot be reproduced locally
with the same SDK version but manifests consistently on hosted agents.

Since we build separately anyway (--no-build), switch to dotnet exec
which directly invokes the built DLL without any argument parsing
ambiguity.
