Make Codex pet placement customizable, including secondary-monitor support

What variant of Codex are you using?

Codex App (Windows)

What feature would you like to see?

Please make the Codex pet's on-screen position customizable.

In a multi-monitor setup, I would like to keep the pet visible on my secondary display so it does not obstruct the work on my primary display. Useful controls would include:

• Choosing the monitor where the pet appears
• Choosing a screen corner or freely setting its position
• Remembering the selected position

This would make the pet feel present without covering the editor or chat.

Additional information

While checking the pet, I changed its size and then restored it. It remained around the center of the screen. Hiding and showing it, restarting the Codex App, and switching to another pet did not restore it to a corner. A Reset position option would also be helpful.
