feat: add strict error handling with set -euo pipefail

- Add 'set -euo pipefail' at the top of the script for robust error handling
- Define safe IFS variable to prevent word splitting issues
- Ensures script exits on any command failure (-e)
- Treats unset variables as errors (-u)
- Handles pipe failures properly (-o pipefail)
- Improves script robustness and prevents silent failures

This follows bash best practices for production scripts and makes
debugging easier by failing fast on any unexpected conditions.
