Make triggers incompatible with each other, and clearly mark them in the skill gem dropdown as "inferior/bad"

Is your feature request related to a problem? Please describe.
If a spell/gem already has a trigger, i. e. if there is a spell gem socketed into a wand with the "Trigger a Socketed Spell when you Use a Skill" modifier or already linked to a trigger gem, none of the trigger gems like Cast on Death Support should be presented as a valid choice, because they will outright disable all affected skills if chosen.

Describe the solution you'd like
Trigger gems are marked as "bad/inferior" in the dropdown like when a gem is a net negative to the build, if there is already another trigger applied.

Describe alternatives you've considered
Other than keeping all this in mind none.

L’issue non indica file né test. Inizia individuando il menu a discesa delle skill-gem e la logica esistente per contrassegnare le gemme come cattive o inferiori, quindi segui il modo in cui vengono rilevati i trigger incastonati e collegati. Il lavoro è completato quando le trigger-gem incompatibili vengono contrassegnate chiaramente o rifiutate quando un altro trigger influisce già sull’abilità.
