Missing error handling in pattern.sh

[brianredbeard]

Description

The pattern.sh script lacks set -euo pipefail which means errors in commands won't cause the script to fail, potentially leading to partial or corrupted state.

#!/bin/bash
# Current: no error handling

Expected Behavior

Add strict error handling at the top of the script.
