Add full Ark protocol support as a Bitcoin L2 (coin-only), using the @arkade-os/sdk with Arkadeos server (arkade.computer). Follows the same pattern as the existing Spark integration. Env vars: ARK_PRIVATE_KEY, ARK_SERVER_URL (optional)
- Remove unused reconnectWallet() and reconnectAttempt field - Improve getTransaction() to use finalizePendingTxs() for outgoing tx confirmation instead of only checking VTXOs
The @arkade-os/sdk ships ESM-only sub-dependencies (@scure/btc-signer) that break Jest's CommonJS transform. Add a moduleNameMapper mock following the existing @dfinity pattern.
…apter, and user enum Add ARK cases for payment requests, address detection, signature verification, and balance updates that were missed in the initial integration.
Cover signature verification (valid/invalid/edge cases), balance conversion, transaction lifecycle, health checks, payment request formatting, and not-implemented guards.
