op-geth does not support admin_addStaticPeer; classify op-geth via
compose path (admin_nodeInfo often still says Geth) and fall back on
go-ethereum-style "does not exist/is not available" errors so reinject
and connect-peers restore peers (e.g. hashkey-mainnet).
Add bootstrap-peers.sh and fall back to stakesquid.eu/bootstrap when local peerset capture is empty; optional --seed-bootstrap on connect-peers.
