Add CLI tool for adapter template generation

[uwezukwechibuzor]

Summary

Added an interactive CLI tool to auto-generate pegged asset adapter boilerplate

What's New

Command:

npm run create-adapter

Two modes:

• Interactive - Guided with prompts
• Non-interactive - One-line command with flags

npm run create-adapter -- \
  --name "PUSD" \
  --id "pusd" \
  --chains "ethereum,bsc" \
  --addresses "0x...,0x..." \
  --types "m,b"

Generates:
index.ts - Properly configured adapter
README.md - Complete documentation

Key Features
✅ supports all chains in chain.json
✅ 18 peg types (USD, EUR, GBP, etc.)
✅ Minted/bridged token handling
✅ Reserve address configuration
✅ Duplicate adapter detection

Edge cases (duplicates) ✓

Example Output

Generated index.ts:

import { addChainExports } from "../helper/getSupply";

const chainContracts = {
  ethereum: {
    issued: ["0x..."]
  },
  bsc: {
    bridgedFromETH: ["0x..."]
  }
};

const adapter = addChainExports(chainContracts, undefined, {
  pegType: "peggedUSD",
  decimals: 18,
});

export default adapter;
