Minimal changes from upstream xmrcheckout to support Wownero: - Rate provider: Nonlogs WOW-BTC via Kraken BTC/USD - Subaddress derivation: Wownero network byte overrides (53/63/54) - Payment URI scheme: wownero: - Dockerfile: Wownero binaries from Codeberg - Display text: Monero→Wownero, XMR→WOW throughout UI - Default daemon: 192.168.88.235:34568 - Added wownero-logo.svg File and folder structure kept identical to upstream for easy sync.
