Description

Enables publishing infrastructure for .NET 11 Preview channels 1-7. Channels were created in Maestro (IDs 9581-9594) but lacked publishing configuration in arcade.

Changes

  • PublishingConstants.cs: Added 14 TargetChannelConfig entries
    • 7 runtime channels: .NET 11 Preview N (9581, 9583, 9585, 9587, 9589, 9591, 9593)
    • 7 SDK channels: .NET 11.0.1xx SDK Preview N (9582, 9584, 9586, 9588, 9590, 9592, 9594)
    • Uses DotNet11Feeds (dotnet11, dotnet11-transport, dotnet-eng, dotnet-libraries, dotnet-tools)
    • aka.ms paths: 11.0-previewN and 11.0.1xx-previewN (using previewN format without dot)
    • Public visibility with UnifiedBuildAkaMSDoNotCreateLinkPatterns

Pattern follows existing .NET 10 RC channel configurations.

Updated all channel names to use "previewN" format (without dot) in commit a29dc55. All 14 channels now use "11.0-previewN" and "11.0.1xx-previewN" naming.
