- [ ] 2.2 RED+GREEN: leader progress initialized on becoming leader
- [x] 2.2 RED+GREEN: leader progress initialized on becoming leader
- Test: after a node becomes leader, `next_index[j] == log_len + 1` and `match_index[j] == 0` for every peer (raft.tla BecomeLeader)
- Implement the `next_index`/`match_index` initialization on the win path (`raft_start_election` single-node + the multi-node become-leader transition)
- Observable completion: assertion on `next_index`/`match_index` after election passes; no regression in election tests
