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

gen-cordis-catalog/api, config and persistence catalogs, and doc graphs
regenerated over the new sessionProjectionCache service and the registry's
checkpoint faces. Classifications: ProjectionCheckpoint joins the type-link
exemptions (owned by the projection package source), Partial joins the
foundation names, the cache service gets its capability-seam role row, and
the package takes the one-sentence Model Experience contract (host-side
read-model accelerator, no model surface).
