function runArduPilotPatch(rootPath, vehicleType)
% RUNARDUPILOTPATCH Apply Simulink patch to ArduPilot for the given vehicle type.
%   runArduPilotPatch(rootPath, vehicleType)
%
% Inputs
%   rootPath    - absolute or relative path to the ArduPilot repository root (char)
%   vehicleType - 'Copter' or 'Plane' (case-insensitive) (char)
%
% Behavior
%   - Validates inputs and locates a JSON configuration file named
%     "<vehicleType>_modification.json" in the same folder as this script.
%   - Calls applyCodeInsertions(rootPath, jsonPath) to apply tag-based edits.
%   - Copies the AC_Simulink folder contents from the script directory 'common'
%     into the repo at libraries/AC_Simulink.
