docs: regenerate catalogs and graphs for the projection seam; classify its types

gen-cordis-catalog type-link rows for the ProjectionDefinition surface and
CommandExecution; a sessionProjections service-role row for gen-doc-graphs;
regenerated module graph, persistence/config/cordis catalogs and api-catalog;
packages/README rows condensed back under the word ceiling; the RFC's sketch
fences marked ignore-check on both language sides (pairing re-recorded).
