Long CI is mostly due to examples with hard-coded patches: An easy fix about 1 year ago

AI Summary: The task involves optimizing the continuous integration (CI) process for the MFC project by refactoring example cases. Currently, the CI process is slow because it rebuilds the simulation for each example with a hard-coded patch. The solution is to move these hard-coded patches into the source code's include directory, eliminating the need for repeated compilation during testing. This will significantly reduce the CI runtime.

Complexity: 3/5
