The cloud websocket was established once during sign-in and never
re-established. On any server restart or transient network drop the
connection task exited. yawc itself does not reconnect.
This wraps `connect_to_cloud` in a long-lived task that re-establishes
the websocket with exponential backoff and jitter, reusing
`INITIAL_RECONNECTION_DELAY` and `MAX_RECONNECTION_DELAY` so the
behavior matches the Collab reconnect loop in the same module.
Part of CLO-713.
