AI Modification Log: Build Result Detection

Date: 2026-06-29

Change

• Updated X/Y/Z workflow build steps to use set -o pipefail before make | tee.
• Captured the build status immediately after the primary build or fallback build.
• Appended fallback build output to build_log.log.
• Moved the Z workflow mosdns CGO_ENABLED=1 fix before make runs.

Reason

Without pipefail, make | tee could report success when make failed. In the Z workflow, the mosdns fix ran after make, so it was applied too late and the final $? reflected sed instead of the build result.
