The multi-connection registry (Settings -> Connections) shipped with no
entry point outside the settings nav, and the product-owner report was
blunt: 'I didn't see any obvious way to hook up multiple gateways.'
- Profile rail: a plug pill pinned beside Manage ('Connect another
Hermes gateway...') deep-links to /settings?tab=connections. Always
visible, including for single-profile first-run users.
- Command palette: Settings -> Connections is now a searchable entry
(keywords: add gateway, remote, ssh, cloud, instances, registry).
- i18n: profiles.connectGateway added to en/types/zh; other locales
fall back through defineLocale.
- Tests: profile-rail-connect.test.tsx covers the deep link and the
single-profile visibility guarantee.
