[macOS] Global Control+Space shortcut conflicts with input-source switching and summons Codex Pet

What issue are you seeing?

After a recent Codex desktop update, Control+Space is registered as a global shortcut for summoning the Codex Pet.

On macOS, I use Control+Space to switch keyboard input sources/languages. Now, every time I change the input language, the Codex Pet appears—even when Codex is not the focused application.

This is a regression and creates a system-wide shortcut conflict.

What steps can reproduce the bug?

1. In macOS System Settings, configure Control+Space for switching input sources.
2. Launch Codex and leave it running in the background.
3. Focus another application.
4. Press Control+Space to change the keyboard language.
5. Observe that the Codex Pet appears even though Codex is not focused.

What is the expected behavior?

Changing the macOS input language should not summon Codex.

Codex should avoid silently assigning a global shortcut that conflicts with an existing macOS shortcut. The Pet shortcut should be configurable or disableable, and Codex should detect and warn about shortcut conflicts.

Updates should not introduce new global shortcuts without user confirmation.
Every Control+Space press summons the Codex Pet globally, including while another application has focus.

Additional information

This started after a recent Codex update and did not happen previously.

Start by reproducing the conflict on macOS with Control+Space configured for input-source switching, then locate the Codex Pet global-shortcut registration entry point. Trace how the shortcut is assigned and whether configuration or conflict handling exists. Done means input-source switching no longer summons the Pet, with the requested shortcut behavior addressed.
