The renderer made a single gateway.connect() call during boot, so a
freshly spawned backend that was still initializing (event loop blocked
15-30s by MCP connects and plugin discovery) made the one dial lose and
boot ended in the 'Could not connect to Hermes gateway' modal even
though the backend became healthy moments later. Retry the initial dial
with bounded attempts, re-minting the WS URL on every attempt (OAuth
tickets are single-use), and propagate reauth failures immediately.
