Research direction

Start by locating how the plugin currently validates @Mapping values and integrates editor inspections. Determine which incorrect mappings should produce errors and how severity, disabling, and suppression should work. Done means incorrect mappings are highlighted in the editor with the requested inspection controls.

Written by the indexing model from the issue text.

Description

It would be great if the plugin could highlight incorrect mappings with an error directly in the editor.

An inspection would be a good way to implement that I think. (For example the user can then enable/disable it, configure the severity and supress it at specific occurrences if needed.)
