KBE authoring guidance (ci-failure-scan)

• Error Details is for readers. The exception and stack trace below make the failure understandable without opening the raw log.
• Build Analysis parses only the single JSON block under Error Message.
• ErrorMessage contains case-sensitive ordinal String.Contains substrings copied verbatim from the failing log.
• BuildRetry is false because this is a test failure rather than a clear infrastructure retry case.
