Subject: refactor(io): model ask_and_validate validators with anyhow::Result

PHP's askAndValidate throws when a validator rejects input. Change the
IOInterface validator callback and return type to anyhow::Result so the
call sites can return Err instead of panic, faithfully modeling the throw
semantics already supported by the Question layer.
