Influencer Collaboration Group

Each entry of creators is [name, followers]. Each entry of collaborations is [name1, name2], an undirected link between two creators. Two creators are in the same group if they are connected through a chain of collaborations; a creator with no collaborations is a group of one.

A group's total is the sum of its members' followers. Among groups whose total is at least minimum_followers, return the group with the largest total, as a list of member names sorted ascending.

• If several qualifying groups tie on the total, return the one whose sorted name list is lexicographically smallest (compare the lists element by element, like Python list comparison).
• If no group qualifies, return [].
• Collaborations that mention a name not in creators are ignored. A collaboration may be listed more than once.
