Migration Pattern

// Before
import { start } from 'solana-bankrun';
const context = await start([...]);
const client = context.banksClient;

// After  
import { LiteSVM } from 'litesvm';
const svm = LiteSVM.default();
svm.addProgramFromFile(programId, 'path/to/program.so');

For Anchor tests:

// Before
import { startAnchor } from 'solana-bankrun';
import { BankrunProvider } from 'anchor-bankrun';

// After
import { LiteSVM } from 'litesvm';
import { LiteSVMProvider } from 'anchor-litesvm';
