investigate if we can intercept saving changes in EF to catch changes to the model

[hahn-kev]

This could mean that the dev provides a diff callback for each type which returns a list of changes. But otherwise using it would look just like using EF normally. Here's what this might look like

public IEnumerable<IChange> Diff(Word? oldWord, Word newWord)
{
    if (oldWord is null) return [new NewWordChange(newWord.Id, newWord.Text, newWord.Note)];
//etc...
}

public async Task CreateWord(Word word)
{
    DbContext.Set<Word>().Add(word);
    await DbContext.SaveChangesAsync();
}

we would just need to intercept the save event then call the Diff method defined by the user.
