Right Alt/AltGr does not produce Polish characters on Windows 11 (v0.36.0)

Summary

On Windows 11, the Codex 0.36.0 desktop binary ignores the right Alt (AltGr) modifier. As a result, it’s impossible to
enter Polish letters such as “ą”, “ę”, “ł”, etc. when using the standard Polish Programmers layout. I’ve seen the same
behaviour on an earlier release (pre-0.36.0, exact version not noted), so this isn’t a recent regression.

### Steps to reproduce

1. Install/run Codex 0.36.0 on Windows 11 24H2 (AMD64, build 26100.6584).
2. Switch the keyboard layout to Polish (Programmers).
3. Focus any text input inside Codex (e.g. editor, terminal).
4. Press Right Alt + a.

### Expected result
The application respects the AltGr modifier and inserts “ą” (or the appropriate Polish character for the combination).

### Actual result
Codex ignores the AltGr modifier and either types a plain “a” or does nothing. The only way to enter Polish characters
is to fall back to the one-handed dead-key sequence (e.g. Shift + ` ` followed by a`), which is much slower.

### Environment

• Codex version: 0.36.0 (Windows binary from GitHub release)
• OS: Windows 11 24H2 (AMD64) build 26100.6584
• Keyboard layout: Polish (Programmers)

### Workarounds
Using the dead-key sequence (Shift + ` `` then the base letter) still works, but it slows down typing. Toggling
the in-app setting related to the right Alt key (treating right Alt as AltGr) has no effect.

### Additional context

• Also reproduced on an earlier Codex release (before 0.36.0), though I no longer have the exact version at hand.
• The same system running Codex inside WSL handles AltGr correctly, so the issue appears specific to the native

Windows build.

• No custom modifications or third-party key mapping utilities are in use; the same hardware and layout work as

expected in other Windows applications.
