OpenBot 0.57.0 Adds Branching, Undoable Instructions

This is a strong workflow release that makes long-running agent collaboration more inspectable and recoverable.

• –Conversation branches let developers explore alternate approaches without altering the original thread, while workspace files remain shared.
• –Editable AGENTS.md instructions turn agent behavior into a visible, maintainable artifact rather than hidden configuration.
• –Undo after instruction changes provides an important safety net for teams iterating on agent behavior.
• –Browser alerts and confirmations opened by an agent no longer automatically halt computer-use tasks.
• –Mobile administration is becoming a real control plane, covering folders, server settings, custom agents, and task-planning behavior.
