MachineX Swap (JavaScript / ethers.js)

Perform a single-pool swap on MachineX (peaq EVM) using the SwapRouter exactInputSingle flow in JavaScript with ethers.js v6.

This README includes:

• Pool discovery via Factory getPool()
• TickSpacing handling (required by router)
• Basic output estimate + slippage-based amountOutMinimum
• ERC-20 approval
• Executing the swap

⚠️ Important: The slot0-based estimate is a rough quote (does not account for price impact, fees, or tick crossings). For production quoting, use an official Quoter/SDK if available.
