The node generates the miner auth token and TLS pin per chain under
<base-path>/chains/<id>/, so the mainnet cutover needs one miner deploy
pointed at the new id (lair/quantus's node deploy prints it). The binary
is unchanged by a chain switch; only the credentials trigger the restart.
CHAIN stays the push-time default and is to be bumped after the cutover.
