test(ipfs): cover the kubo client (#824)

packages/ipfs/src/kubo-client.ts had zero coverage — the second-largest
gap surfaced by collectCoverageFrom in #822, and the largest remaining
after #823. 31 tests take it to 99.1% (115/116).

The class is a thin wrapper over kubo-rpc-client, so the tests mock that
one module and exercise everything else for real: connect and the
readiness wait, content add/get for text, binary and streams, JSON block
round-trips, identity, peer dialling, and peering configuration.

Notable coverage:

- addJSON derives the CID locally from the encoded block rather than
  trusting the daemon, so the tests assert equal payloads yield equal
  CIDs, different payloads differ, and the stored block decodes back to
  the original.
- getAddresses filters private addresses; covered across IPv4 loopback
  and RFC1918, IPv6 loopback, public v4 and v6, and a /dns4/ multiaddr
  that matches no ip pattern and is dropped.
- addPeer rejects a malformed address or a private IP *without dialling*,
  which is the SSRF-shaped guard, plus the unrecognized-response and
  dial-failure paths.
- addPeeringPeer skips self, keeps only dialable addresses, writes
  nothing when none are dialable, and merges into an existing entry
  without duplicating.

waitUntilReady is driven with intervalSeconds: 0 and a maxRetries bound
so the retry loop neither sleeps nor leaves a timer behind — CI runs
without --forceExit.

No findings this time: unlike the sqlite backend, the error handling here
matches what the types promise. Repo total 93.84% -> 95.19%.
