/**
 * Private Swap Recipe — Full pipeline: unshield → approve → swap
 *
 * Orchestrates the complete private swap:
 *   1. Derive Railgun keys
 *   2. Fetch spendable UTXOs → check balance
 *   3. Get swap quote (0x → Aerodrome fallback)
 *   4. Calculate unshield amount
 *   5. Generate ZK proof (client-side Groth16)
 *   6. Build 3-call multicall: [unshield, approve, swap]
 *   7. Build UserOp with paymaster signature
 *   8. Sign UserOp with owner key
 *   9. Submit to EntryPoint
 *  10. Wait for confirmation
 *  11. Return structured receipt
