KBE authoring guidance (ci-failure-scan)

• Error Details is for readers. The excerpt below is copied from the Azure Pipelines timeline issue.
• Build Analysis parses only the single JSON block under Error Message.
• ErrorPattern uses .NET Singleline | IgnoreCase | NonBacktracking matching with a 50ms-per-line timeout.
• BuildRetry is false so this issue does not request a CI rerun.
• ExcludeConsoleLog is true because this is an Azure Pipelines job-timeout issue rather than a Helix console failure.
