 * Consume the generic bot-to-bot `@steer` control directive.
 *
 * The directive must be the first semantic line, optionally following one or
 * more leading @recipient lines emitted by Lark. Both forms are accepted:
 *
 *   @steer
 *   adjust the current task
 *
 *   @TargetBot
 *   @steer adjust the current task
 *
 * This parser is deliberately transport-only and language-neutral. It does not
 * authorize anything by itself; the daemon additionally requires a positively
 * classified foreign-bot sender and applies the existing control-lane gates.
