Implements the NIP-60 specification for cashu-based wallets with four event types:
- CashuWalletEvent (kind:17375) - replaceable wallet definition with encrypted mints/privkey
- CashuTokenEvent (kind:7375) - unspent cashu proofs with NIP-44 encrypted JSON content
- CashuSpendingHistoryEvent (kind:7376) - transaction history with encrypted tag array
- CashuMintQuoteEvent (kind:7374) - optional mint quote state with NIP-40 expiration
Follows the same structural patterns as the NIP-88 polls implementation.
