Fix build script to fail on TypeScript errors

Update measure_time function to properly handle command exit codes:
- Check command success/failure and return appropriate exit code
- Log failure messages with timing and exit code information
- Ensure TypeScript type checking failures stop the build process
- Maintains timing logs for both success and failure cases

This prevents deployment of code with TypeScript type errors by making
test and production builds fail fast when tsc --noEmit reports issues.
