Token Blacklist Checker

Probes eight naming conventions for the same capability, because a token that can freeze you rarely calls it blacklist, then reports both whether an address is restricted right now and whether the mechanism exists at all. Capabilities are detected from selectors in the deployed bytecode, so they are found whether or not you could call them. The distinction the tool is built around is that "not blacklisted today" and "cannot be blacklisted" are entirely different positions to hold a token from. It also handles canTransfer correctly, which reads the opposite way to every other check — false is the bad case there, and treating all booleans alike would report a blocked address as clean.
