Shokunin c37b827e97 netplay rollback: every seat answers the episode handshake ...

The episode kept one peer-baseline / ready / POST latch, so with three or
four seats the first reply answered for everyone, and the one early
BASELINE stash was overwritten by the next seat's. In R4's 4-peer run with
the host loaded every frame, two guests replayed a light-tip episode and
resumed while the host had not opened it; host and guests then waited on
each other (pcap_freeze / wire_hole) until the stall timeout.

- BASELINE, ready-ACK and POST go through rnet_rb_quorum: the episode moves
  on only when every other occupied seat has answered, and a digest from
  any seat that differs fails the comparison. Early BASELINEs stash per
  seat. Two seats behave as before.
- Light tip skips the ready RTT only with one peer; with more, every seat's
  ready is how the others know it rolled back to the same load.
- A follower that has not simulated the load tick yet defers and joins when
  it gets there (no NACK, no zombie-load refusal for that join).
- Seal, ready and verify timeouts restart while a seat still owing a reply
  advances its input tip: they fire only when nothing moves.
- psx_netplay_peer_seats(); pins recomp-net rb_quorum.
