Why not ask the customers? It's great you have some traction and their actions are leading you to a direction where they find value. Lean into that!
In any event, no need to make drastic changes. Maybe idea 1, but definitely not wholesale changes like 2 and 3. There are plenty more options on the table, such as:
* make two submit buttons in chat area (chat vs mindmap)
* support very specific mindmap commands and use simple string matching for intent detection (not models)
* create a way for people to choose either chat or mindmap commands for the right hand sidebar
* add more example inputs (like the "show me a summary") to guide the users
