%% Test Script - Verify CI scripts functionality
%
% This script performs pre-flight checks to ensure the CI/CD environment
% is properly configured before running the full build and test pipeline.
%
% Tests performed:
% 1. Verify all required files exist in correct locations
% 2. Confirm MATLAB path configuration
% 3. Test parameter file loading
% 4. Validate model can be opened
%
% Usage:
%   Run this script from the project root directory before executing
%   ci_build() or ci_test() to ensure the environment is ready.
