WHY IT NEEDS A POLICY

Why create_window needs a policy

This tool creates a new tmux window within an existing session. It is a reversible write operation — windows can be killed/removed afterward. It does not execute commands, delete data, or have financial implications. The blast radius is low since it merely adds a UI construct within tmux.
