v2.3.4 Two vote-reliability fixes (MRs !165, !166). - Vote: a broadcast error no longer erases the user's own vote unless the node contradicts it. blurtjs retries the same signed transaction, so a vote that was already applied comes back as "identical to this vote", and a timeout or a 5xx reply gives no verdict at all; both used to clear the optimistic vote, emptying the heart for a vote that was on chain and carrying that stale copy between views. The rollback now asks the node who voted before reverting, and never reverts when the node cannot answer. - RPC: failover now fires when a node is unreachable. transport.send() reported its failures only through its own callback, so error_count never reached failover_threshold and the client stayed pinned to a dead node. The retry budget is bounded too (it was the library default of 10, backing off to about 17 minutes), so the threshold is reached in seconds.
