Issue: codex login hangs on MSYS2

Environment:

Problem:
Running:

codex login

opens the browser and redirects to:

http://localhost:1455/auth/callback?code=XXXXXX

but the CLI never completes login and hangs waiting for the callback.

Notes:

  • Works normally in Windows CMD and PowerShell.
  • Fails only inside MSYS2 / MINGW64.

Expected:
CLI should capture the callback and finish authentication.

Actual:
CLI hangs indefinitely with no error.
