How do I disable mining in `bcoin`? When running bcoin, how does one disable mining by default? I just want to run a full node without mining. There seems to be no config options to control it.
Mining is disabled by default, it must be switched on with RPC commands:

Keep in mind without additional hardware, bcoin can only effectively generate blocks on test networks (like simnet and regtest). A bcoin full node can be used by a mining pool operator to generate block templates and ultimately find valid blocks, there has been at least one block mined on mainnet with a bcoin full node.
