Is this destination a lookalike of an address the sender already trusts? Applies the addre
Is this destination a lookalike of an address the sender already trusts? Applies the address-poisoning similarity rule (leading and trailing characters that wallet UIs abbreviate to) between one destination and a caller-supplied list of known-good addresses. Pure string comparison when `known` is given, so it answers in milliseconds and never runs a scan.
