The last line of the build script uses grep to display built images,
but with set -e, grep returning no matches causes the entire script
to fail. This is a classic set -e footgun.
The grep pattern was also broken: docker images shows REPOSITORY and
TAG as separate columns (no ':' between them), so 'xiaoxia-saas.*:'
never matched. Changed to two-stage grep and added || true safety net.
The build and push were actually succeeding - only the final display
line was causing the failure.
