New workflow node: Add / Remove user in list

You can now dynamically update list users as part of workflow execution. This is a step toward creating user segments based on events or workflow progression, removing the need to call the List Update API separately.

Key use cases

1. Event-based segmentation- When an event occurs, trigger notification to the user and simultaneously add them to a list for future updates. For example, when a user registers for an upcoming event or webinar, you can send them confirmation email and add them to a list to later send further updates related to the event.
2. Workflow Step-based segmentation - Another use case is dynamically adding or removing a user from the list when they complete a workflow step. For example, in a knowledge series designed to onboard new users, remove a user from the POC list once they complete onboarding.
