v0.3.2

Fixed

• Offline receive matched none of the registry's corridor cards — solver selection queried the market set by exact leg id (arkade:<network>/slip44:<slip> / bolt11:<network>/slip44:<slip>), but the published registry indexes its corridor cards in the legacy v0 shape (base_asset.id: "btc" + quote_corridor: "lightning"), whose leg keys render as arkade:btc/lightning:btc. selectMarkets compares leg keys as strings, so the two never met and every offline receive answered no solver card supports a N sat lightning receive. Selection now delegates to solverLightningRendezvous, which accepts both id forms and also rejects a market whose base leg is not BTC — a check the corridor test alone cannot make. The runner-up candidates are still returned in ranked order, so per-quote solver failover is unchanged; the emulator x-only key is now a required argument, since the covenant commits to it. A regression test pins the registry's live short-id shape.
