machines.starkstrom: announce pins to IPNI so public gateways can serve them
Measured with ipfs-check against a pinned CID: DHT record present,
bitswap answering, no IPNI record, and every public gateway 504ing on
anything bigger than one block -- a DAG walked block by block over
bitswap from a single peer does not fit their request budget. The old
node (2configs/services/flix/ipfs.nix) ran Routing.Type autoclient,
which announces to cid.contact as well as the DHT, plus Provide
strategy pinned; mirror that and its swarm sizing.
