Execute an approved ClickUp merge and rewire linked dependencies

Turns an approved merge decision into safe ClickUp changes. It reads which task is the keeper and which are duplicates, then repoints every blocking/waiting-on dependency and linked relationship from the duplicates onto the keeper, comments a merge note on each duplicate, and closes them. A summary of every rewired edge goes back to Slack.

Use it as the action half of a dedupe workflow once a human has confirmed a merge. It removes the manual, error-prone step of hand-copying dependencies before closing duplicates — the part where links usually get dropped.

1. 1A Slack approval (button or webhook payload) triggers the run with keeper and duplicate task IDs.
2. 2ClickUp returns each duplicate's dependencies, linked tasks, and subtasks.
3. 3A logic step computes the rewire plan, skipping edges that already point at the keeper to avoid self-loops.
4. 4ClickUp applies the new dependencies, adds a merge comment, and sets duplicates to a closed status.
5. 5Slack receives a confirmation listing every dependency moved and task closed.
