Add v6 node-class markers (Stage 2 foundation for progressive loading)

Browse Source 
Each top-level node is wrapped in a marker carrying its class (infrastructure vs
visual) and byte span, so the reader can serve or skip a whole node per load pass
without knowing its terminator token. The bake recognizes nodes by the "node"
keyword + type token (map type->terminator confirmed against the deserializers)
and classifies them; the writer buffers a node's entries and emits the marker.
The reader gains a pass selector (all / infrastructure / visual) and skips nodes
not in the pass by advancing past their byte span.

This is the foundation only: the default pass is "all", so loading is identical
to v5 (markers are transparent) -- verified by loading td.scn to the same point.
The eager/visual split is wired up by the upcoming loader/driver integration.
