/**
 * Strip leaked reasoning prose from Nemotron-family models.
 *
 * NVIDIA's Nemotron Omni reasoning model emits its chain of thought as plain
 * text — without `<think>` tags or a separate reasoning_content channel — so
 * the think-tag stripper can't catch it. The reasoning prose is then concatenated
 * directly with the answer (often without even a separator), e.g.:
 *
 *   "The user asks: ... According to instructions, we must obey. Just output
 *    the tokenOMNI_E2E_OK"
 *
 * This module detects the reasoning preamble (heuristic: leading sentence
 * matches a known meta-reasoning opener) and strips everything up to and
 * including the last "answer-introducer" phrase ("just output the token",
 * "the answer is:", "output:", etc.). The stripped portion is returned as
 * `thinking` so it can be routed to the thinking display channel; the
 * remainder is the user-facing `answer`.
