Add a command for coin contract addresses across chains

[PaulRBerg]

Problem

I wanted to use cg to answer: "what contract addresses does this coin use across all chains where CoinGecko lists it?"

For example, given a CoinGecko coin ID like usd-coin, it would be useful to get the platform-to-contract mapping currently available from the API via /coins/{id} (platforms / detail_platforms) or /coins/list?include_platform=true.

Today the CLI covers search, price, markets, trending, history, etc., but this specific coin metadata lookup still requires calling the API directly after resolving the coin ID.

Suggested solution

Add a command or flag for this, e.g. one of:

cg contracts usd-coin -o json
cg coin usd-coin --platforms -o json
cg search usd-coin --include-platforms -o json

A JSON shape like this would be enough for scripting:

[
  {
    "platform": "ethereum",
    "contract_address": "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48"
  }
]

If backed by detail_platforms, an optional detailed mode could also include fields like decimal_place where CoinGecko exposes them.

Why this helps

This is handy for agents/scripts that need to normalize a coin to on-chain addresses across EVM and non-EVM platforms. It would make cg more self-contained for coin discovery workflows: search for the coin ID, then ask the CLI which chains/contracts CoinGecko knows about.
