Add tokenList.js with 511 ERC-20 tokens ranked by market cap

Browse Source

New module with top Ethereum mainnet ERC-20 tokens sourced from
CoinGecko API (market cap ranking) with decimals verified on-chain
via eth_call to each contract. Addresses are EIP-55 checksummed.

Exports:
- TOKENS: full array ordered by market cap
- TOKEN_BY_ADDRESS: Map of lowercase address -> token info
- KNOWN_SYMBOLS: Map of uppercase symbol -> legitimate address
- getTopTokens(n): return first n tokens

This module is not yet integrated into the existing token.js — it
exists alongside it for now as a data source ready for integration.
