docs: dire partout que la lecture par lot n'existe plus

Le contrat publie et l'api-contract etaient traites avec le retrait lui-meme ;
restaient les documents qui decrivaient readUnion comme la primitive de
lecture du paquet, ou qui nommaient le module disparu.

Ce que les lecteurs apprennent maintenant : lire un document, c'est
docs.sparqlQuery ancre dessus, et lire plusieurs documents, c'est cet appel
une fois par document -- avec la decision sur une lecture qui echoue ecrite
au point d'appel. Deux consequences sont dites plutot que decouvertes : une
lecture refusee leve au lieu de rendre une liste vide, et les sujets sous le
prefixe reserve urn:ng-eventually: reviennent dans le resultat, a l'appelant
de les ignorer -- sans aucun gain de droits, les deux registres qu'un
document ordinaire porte etant l'adresse de sa boite et, pour un document
public, la cle que son magasin sert deja a qui la demande.

Les briefs dates ne sont pas touches : ils decrivent un etat de juillet, et
le reecrire falsifierait ce qui avait ete decide alors.
