Before You Upgrade S/4HANA: Static UI5 Checks with MCP

Series note: This post is part of my AI ABAP development series. It reuses the legacy UI5 app from the SEGW to RAP migration demo, but this time the focus is only on the UI5 version upgrade problem. In the SEGW to RAP post I used a deliberately old freestyle UI5 app as migration material.
