[MTP CLI Analysis] --hangdump-type help advertises target-dependent values incorrectly #8431

Summary

--hangdump-type help and validation text advertise the wrong valid-value set for some target frameworks. The shared resource strings say Triage is valid and that None is only available in .NET 6+, but the actual validator uses a different conditional list.

Evidence

• src/Platform/Microsoft.Testing.Extensions.HangDump/HangDumpCommandLineProvider.cs:19-23

  #if NETCOREAPP private static readonly string[] HangDumpTypeOptions = ["Mini", "Heap", "Full", "Triage", "None"];
  #else private static readonly string[] HangDumpTypeOptions = ["Mini", "Heap", "Full", "None"];

• src/Platform/Microsoft.Testing.Extensions.HangDump/HangDumpCommandLineProvider.cs:52-57

  if (!HangDumpTypeOptions.Contains(arguments[0], StringComparer.OrdinalIgnoreCase)) { return ValidationResult.InvalidTask(...); }

• src/Platform/Microsoft.Testing.Extensions.HangDump/Resources/ExtensionResources.resx:189-197

  Valid values are 'Mini', 'Heap', 'Triage', 'None' (only available in .NET 6+) or 'Full'.
  Valid options are 'Mini', 'Heap', 'Triage', 'None' (only available in .NET 6+) and 'Full'

• est/IntegrationTests/Microsoft.Testing.Platform.Acceptance.IntegrationTests/HelpInfoAllExtensionsTests.cs:95-98

Valid values are 'Mini', 'Heap', 'Triage', 'None' (only available in .NET 6+) or 'Full'.

Why this is a real issue

On a non-NETCOREAPP target, help currently tells users that Triage is valid even though the validator will reject it, because the non-NETCOREAPP list does not contain Triage. The same text also understates None support by calling it .NET 6+-only even though the non-NETCOREAPP branch still allows None. That is a concrete help/validation mismatch, not a theoretical cleanup.

Suggested resolution

Generate or select the valid-value help text from the same target-specific source used by the validator. At minimum, make the resource text match the #if NETCOREAPP / #else option lists so the help output and error messages stop promising values the validator rejects.
