Subject: [PATCH] Add close button to Studio plugin windows.

Plugin windows could only be closed from the Plugins menu. Pass the
plugin's active flag to ImGui::Begin so the window gets a close button
that writes the same persisted state as the menu toggle. Skip the
update callback while the window is collapsed.
