… and retry (MettaChain#244) Implement StellarOptimizationService providing: - Connection pool (size=5) with acquireConnection / releaseConnection and automatic replacement of connections exceeding the error threshold - Transaction queue with priority ordering (high > normal > low) and timed flushBatch flushing every 2 s (up to 10 txs per flush) - submitWithRetry with configurable exponential back-off (default 4 attempts) - Network health monitoring for both mainnet and testnet horizons on a 30 s interval with automatic failover to testnet when mainnet is down - getPoolStats and getNetworkHealth for observability
