Add Smart Transactions support to Jupiter swaps

Fixes #199

Adds Smart Transactions support to executeJupiterSwap and merges Jupiter API improvements from #204.

Changes

  • Added useSmartTransaction parameter for enhanced reliability during network congestion
  • Merged Jupiter Lite API endpoints and improved error handling from Update Jupiter API endpoints and enhance error handling in RpcClient … #204
  • Restored complete priority level support: low, medium, high, veryHigh, unsafeMax
  • Smart Transactions automatically handle priority fees and compute units when enabled

Usage

const result = await helius.rpc.executeJupiterSwap({
  inputMint: 'So11111111111111111111111111111111111111112',
  outputMint: 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v',
  amount: 10000000,
  useSmartTransaction: true, // New parameter
  priorityLevel: 'veryHigh',
}, wallet);

Defaults to false for backward compatibility.

Benefits

  • Better success rates during network congestion
  • Improved performance with Jupiter Lite API endpoints
  • Enhanced error handling and validation
  • Full priority level control
  • Zero breaking changes (defaults to false)

Testing

  • ✅ All existing tests pass
  • ✅ TypeScript compilation successful
  • ✅ Lint and format checks pass
