## ActionRegistry - Registry of director action templates (Phase 3c).
##
## Single source of truth for the action types the Director Tool and the event
## system understand. Adding a new action type is just appending an entry here;
## the ActionEditor and the panels generate their UI from this registry, so no
## other code changes are required.
