Pull Request Overview

This PR adds job information logging to system log messages for AI error explanation functionality. The changes help identify which specific job/build the log messages relate to by including job name and build number in log entries.

• Extracts job information (job name and build number) at the start of both error explanation methods
• Updates all LOGGER statements to include the job info prefix for better traceability
• Updates user-facing error messages to include job context
