### Description

(This is a smaller issue that continues from https://github.com/ipfs/go-ipfs/issues/9043, and a `ipfs daemon` equivalent to https://github.com/ipfs/ipfs-webui/issues/1964)

Currently, `ipfs daemon` prints `Swarm announcing` for the initial, local multiaddresses. However, when using `RelayClient`, public multiaddresses aren't found until after `Daemon is Ready` and so are never reported.

Ideally, `ipfs daemon`'s output should report additional `Swarm announcing` messages for multiaddresses found after it reports `Daemon is ready`.

Start at the `ipfs daemon` startup path and examine how initial `Swarm announcing` messages and `Daemon is ready` are emitted. Trace how `RelayClient` discovers public multiaddresses after readiness. Done means later-discovered multiaddresses produce additional `Swarm announcing` output.
