The rename to /v1/chain is real in luxd source, but the deployed fleet has not
taken it yet: probed just now, api.lux.network, api.lux-test.network,
api.zoo.network and api.hanzo.network each answer 200 on /v1/bc/C/rpc and 404 on
/v1/chain/C/rpc. Composing /v1/chain against those hosts reaches nothing, which
is the failure the rename set out to prevent.
The move belongs with the node redeploy, not ahead of it.
