Bulk Token Metadata Reader

Reads the basics for every token in a list and optionally a holder’s balance in each. Kind is decided by supportsInterface where the contract implements it and otherwise by whether decimals() answers, because plenty of older tokens never implemented the interface check and relying on it alone misclassifies them. The finding that only appears in bulk is duplicate symbols: two different contracts using the same ticker is exactly how an impersonating token passes a quick glance, and checking tokens one at a time never surfaces it. Addresses can be pasted, uploaded, or pulled straight off the page you are looking at, which makes it quick to check every contract mentioned in an article or a listing before trusting any of them.
