Examples:
  auths config show                               # View all settings
  auths config get passphrase.cache               # Check caching status
  auths config set passphrase.cache always        # Cache passphrases

Valid Keys:
  passphrase.cache       — 'never', 'session', 'always'
  passphrase.duration    — seconds until cache expires
  passphrase.biometric   — 'enabled', 'disabled' (macOS)
