A router answers name lookups by reading the blockchain through a node of its own, and that node can lag — we measured smp7 answering correctly for older records while not yet seeing a text record set seconds earlier. Without knowing how current an answer is, a client cannot tell "this name is available" from "this name was available as of some unknown point in the past", which is exactly wrong in the case that matters most: a user who has just registered a name and is immediately told it is free to register. This PR adds readAt, the block timestamp the registry was read at, to every RNAME answer, so a client can compare it against its own transaction and say "not visible yet" rather than quoting a price for a name the user already owns.
