Pull Request Overview

This PR adds devnet support to the Kobe Cranker by implementing cluster-specific configuration and program ID handling. The changes enable the cranker to operate on different Solana networks (mainnet, testnet, devnet) with appropriate SPL stake pool program IDs.

• Added cluster field to Config struct for network-aware operations
• Modified program ID selection logic to use devnet-specific SPL stake pool program for devnet
• Updated cluster parsing to support devnet network and changed default fallback behavior
