Codex App macOS: traffic-light window controls do not perform standard actions

Bug description

In the Codex desktop app on macOS, the native-looking red/yellow/green window controls in the upper-left corner do not perform the standard macOS window actions.

Observed behavior:

• Green button does not make Codex enter full screen.
• Yellow button does not minimize the Codex window to the Dock.
• Red button does not close/quit the Codex app as expected.

Steps to reproduce

1. Open Codex desktop app on macOS.
2. Click the green upper-left window control.
3. Click the yellow upper-left window control.
4. Click the red upper-left window control.

Expected behavior

The window controls should behave like standard macOS traffic-light controls:

• Green enters full-screen mode.
• Yellow minimizes the window to the Dock.
• Red closes the window, or otherwise performs the standard close/quit behavior expected for the Codex app.

Actual behavior

The controls are visible, but clicking them does not trigger the expected standard macOS actions.

Environment

• Component: Codex desktop app for macOS
• Codex App: 26.608.12217
• Bundle version: 3722
• Bundle identifier: com.openai.codex
• Bundled Codex CLI: 0.138.0-alpha.7
• macOS: 15.7.7 (24G720)
• Architecture: arm64

Additional context

This is distinct from visual clipping/truncation reports for the top-left controls. The issue here is functional behavior: the controls do not perform close/minimize/full-screen actions in the standard macOS manner.
