Fix API approval test: IEvent inherits from IMessage

[Copilot]

API approval test fails because NServiceBus.IEvent inherits from NServiceBus.IMessage. PublicApiGenerator correctly emits both interfaces, but the approved baseline only listed IEvent.

Changes

• Updated APIApprovals.PublicClr.approved.txt to include both IEvent and IMessage for all 10 contract classes

The generated API signature is:

public class CustomCheckFailed : NServiceBus.IEvent, NServiceBus.IMessage

This matches how C# represents interface inheritance in reflection/metadata - derived interfaces are explicitly listed alongside their base interfaces in the public API surface.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• f.feedz.io
  • Triggering command: /usr/bin/dotnet dotnet test --no-build --verbosity normal (dns block)
  • Triggering command: /usr/bin/dotnet dotnet build ServiceControl.Contracts.sln --configuration Release (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
