Update NativeInterop baseline and fix devapp version ranges

[Copilot]

Changes proposed in this request

NativeInterop references were partially updated, and the first pass at making the devapp projects float introduced NU1604 during restore. This update keeps the repository baseline at 0.20.6 and changes the devapp projects to a valid open-ended NuGet range.

• Central baseline

  • Directory.Packages.props
  • Keep MSALRuntimeNativeInteropVersion at 0.20.6

• Devapp package resolution

  • tests/devapps/MacConsoleAppWithBroker/MacConsoleAppWithBroker.csproj
  • tests/devapps/MacMauiAppWithBroker/MacMauiAppWithBroker.csproj
  • Replace invalid floating configuration with an inclusive lower-bound range

• Why this shape

  • tests/devapps disables central package management
  • These projects must use Version=... instead of VersionOverride=...
  • [0.20.6,) preserves “latest available >= 0.20.6” without triggering NU1604

<PackageReference Include="Microsoft.Identity.Client.NativeInterop" Version="[0.20.6,)" />

Testing

• Restored and built tests/devapps/MacConsoleAppWithBroker/MacConsoleAppWithBroker.csproj
• Restored tests/devapps/MacMauiAppWithBroker/MacMauiAppWithBroker.csproj

Performance impact

None.

Documentation

• All relevant documentation is updated.
