Wait for the next inbound SMS and return it, or time out.
The await-reply half of the "send OTP → await reply" pattern: pair it with
sendMessage to send a code and block until the recipient texts back, all
within a single tool-calling turn. Backed by the SDK's presence-based event
stream — for durable delivery, register a webhook instead.
