Feature: Do not trigger the Interaction cooldown when Triggers Actions perform no action.

### For which plugin is the feature?

### Describe your idea

I only want the NPC to trigger Actions via RIGHT_CLICK, with interaction_cooldown set to 10 s. However, some players click the left mouse button, which still triggers interaction_cooldown even though I haven’t assigned any LEFT_CLICK Actions to the NPC. This confuses players, since no Action fires yet the cooldown still applies. I’d like Triggers that have no Actions to be exempt from triggering interaction_cooldown.
