not getting sing-in options with organization login.

### Environment

```yaml

[q-details]
version = "2.21.2"
hash = "a4729fa233d8097438cb3dcb4c9c8d2f21cc82d9"
date = "2026-09-08T20:05:47.556045Z (2d ago)"
variant = "full"

[system-info]
os = "macOS 26.6.2 (25G83)"
chip = "Apple M1 Pro"
total-cores = 8
memory = "16.00 GB"

[environment]
cwd = "/Users/USER"
cli-path = "/Users/USER"
os = "Mac"
shell-path = "/bin/zsh"
shell-version = "5.9"
terminal = "macOS"
install-method = "brew"

[env-vars]
PATH = "/Users/USER/.local/bin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/local/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/appleinternal/bin:/pkg/env/global/bin:/opt/homebrew/bin"
SHELL = "/bin/zsh"
TERM = "xterm-256color"
__CFBundleIdentifier = "com.apple.Terminal"
```

まず、macOS 上で q doctor と q restart を使用して Amazon Q Developer CLI 2.21.2 のログインフローを再現し、次にデフォルトブラウザを起動して CLI に戻る認証フローを追跡します。組織のログインオプションが表示され、ブラウザでのサインインによってアプリケーションに正常に戻れば完了です。
