- lnd.closedchannels: closed-channel history via /v1/channels/closed
- channel list now includes waiting-close and force-closing pending
channels with their closing_txid
- closechannel reads the close stream's first update with a dedicated
client instead of hanging until the closing tx confirms; returns the
closing txid in display byte order
