Extends the SSE error switch in frontend/src/client/paliadin.ts'
friendlyErrorMessage to map four new error codes from RemotePaliadin
Service into localised messages:
- mriver_unreachable: mRiver is offline / paliadin-shim unreachable
(DE: "mRiver ist offline — Paliadin nicht erreichbar. Mach mRiver an,
oder nutze Paliadin lokal mit ./paliad."
EN: "mRiver is offline — Paliadin can't reach it. Wake mRiver, or
run Paliadin locally with ./paliad.")
- shim_auth_failed: SSH key / authorized_keys mismatch (Permission
denied)
- shim_error / bootstrap_failed: generic remote-shim failure
- timeout: Claude didn't write the response file in 60 s
Adds the matching i18n keys (DE + EN) plus the type-union entries in
i18n-keys.ts so the t() typecheck stays sound. The old codes
(tmux_unavailable, connection_lost, upstream) are unchanged — local-PoC
deployments keep their existing UX.
Frontend `bun run build` clean: 1886 keys (unchanged sync).
