spirekeeper: add v0.1.3 (pairing seed embeds a machine-reachable bunker relay)

New entry alongside v0.1.2. Fixes the localhost-relay /pair gotcha: a seed
minted via the Pair UI baked ws://127.0.0.1 (lnbits' internal bunker relay)
into bunker_url, unreachable by the remote ATM → BunkerTimeoutError. Now
defaults bunker_relay to the spire's public event relay. See spirekeeper#35;
design follow-up #36.
