[cgo] Component Injection does not work properly

Component injection works only with slight custom editing of the headers and passing raw Refs around, but this is not a good long-term solution. We have no good concept for it now, because it might also involve to include one header by the other header and then use something like go modules to handle the dependencies.

Any help would be super appreciated.

No files, tests, or entry points are named. Start by mapping the cgo component-injection flow and its header and dependency handling, then define the desired inclusion and reference behavior before identifying validation cases for a complete solution.
