This PR modernizes the cross-program invocation example by introducing a new
LiteSVMtest suite and an improved Anchor-based test flow. It removes deprecated Bankrun files, updates @solana/web3.js and related dependencies, and adjusts the TypeScript configuration to ES2020/nodenext for improved tooling compatibility.Changes
