 * Decide whether to wrap the cook now (the "Texas crutch").
 *
 * The advisor reads a trailing series of probe temperatures and combines the
 * current temperature, the wrap window, stall detection, and rate of change
 * into a single call:
 *
 * - `below-window`: under the wrap temperature, so let the bark set first.
 * - `wrap-now`: inside the wrap window and either stalled or barely climbing.
 * - `hold`: inside the wrap window but still climbing well, so wrapping is optional.
 * - `at-target`: at or above the target, so pull and rest instead.
 * - `no-data`: no readings available yet.
 *
 * Pure and side-effect free. Readings must already be in Fahrenheit and sorted
 * chronologically (oldest first).
