/**
 * Live e2e for plugin-xai. Calls the plugin's TEXT_LARGE handler against the
 * real xAI Grok API and verifies:
 *   - a real generation succeeds and contains the expected math answer
 *   - the runtime emits `MODEL_USED` with non-zero prompt/completion token
 *     counts sourced from the upstream usage payload
 *
 * Does not run and prints a yellow warning when `XAI_API_KEY` is not set. xAI is not a
 * supported provider in the shared `describeLive` helper, so this suite
 * uses an inline minimal runtime that satisfies the bits the model handler
 * actually touches (`getSetting`, `emitEvent`, `character`, plus enough of
 * the trajectory plumbing for `recordLlmCall` to return cleanly).
