Adds a third "Hermes Cloud" gateway mode to the desktop app: one portal
sign-in auto-discovers the agents on your account and connects to any of
them with no second interactive prompt.
- Electron: widen connection mode to 'local' | 'remote' | 'cloud', routed
through a centralized modeIsRemoteLike() so every resolution site treats
cloud exactly like remote; portal discovery (GET /api/agents over the
OAuth partition), Privy-cookie liveness, multi-org picker (NAS 409), and a
silent per-agent /oauth cascade (load protected root, not /login).
- Persist a cloudOrg on the cloud block; unselect cloud on mode switch.
- Renderer: Hermes Cloud ModeCard + agent picker (signed-out/loading/empty/
list), org picker, Change-org, connected-highlight + Connected pill.
- i18n (en + zh full; ja/zh-hant inherit via defineLocale), Cloud icon.
- IPC: hermes☁️{status,login,logout,discover,agent-sign-in}.
Salvage of #55402 onto current main: the original branch predates the
desktop electron .cjs -> .ts migration (39d09453f), so the electron half
was re-authored against the .ts files. Authorship preserved.
cloud-auto-discovery Phases 3 + 4.
