Improve build script: Add error handling and DRY cleanup

[czgdp1807]

🛠️ Summary

This PR improves the build script by:

• 🧼 Replacing repetitive os.system(...) calls with a reusable run_cmd() function.
• ❌ Adding proper error handling: the script now exits immediately if any build step fails.
• ✅ Using argparse with action='store_true' for the --clean flag (instead of type=bool).
• 🧪 Ensuring compatibility with CI/CD pipelines by failing fast on errors.

🔍 Why?

Previously, if any command in the build process failed, the script would still exit with code 0 — potentially causing CI to pass despite an error. This PR fixes that and makes the script cleaner and more maintainable.

📦 Affected script

• scripts/build/install.py (or whichever file contains the build logic)

🧪 How to test

python scripts/build/install.py --clean

Try breaking a command manually — the script should exit with an error.
