/**
 * One-shot deprecation warning helper for the messages migration.
 *
 * Components that previously accepted per-string label props (e.g.
 * `saveLabel`, `cancelLabel`, `placeholder`, `addLabel`) keep accepting them
 * during the v1.x deprecation window. When a consumer passes one explicitly
 * we emit a single console.warn per (component, prop) pair so the noise is
 * bounded even if the prop is rebound on every render.
 *
 * Production builds skip the warning entirely.
 *
 * Removed in v2.0 along with the props themselves.
