Error message

Cannot perform this operation because you are in a non-empty session

What it means

Guard in edit_role(): editing the current session's role is only allowed while the session is still empty; if the session already has messages, editing would silently change the role for existing conversation state, so the operation is refused. The state at fault is a non-empty active session with an assigned role.

Solutions

1. Start a new session before editing the role
2. Clear or abandon the current session's messages first
3. Edit the role file directly outside the active session

When it happens

Trigger: Thrown at src/config/mod.rs:971 when the library encounters an invalid state.
