Closes #3

Stacked on #12 (retarget to backend once merged).

Documents in docs/graph-model.md: node types and required properties, relationship types and direction, identifiers, what belongs on nodes vs. relationships, a full example graph, and validation against scenes with several instances of the same class.

Decisions worth reviewing:

  • Directional relations store both directions (LEFT_OF and RIGHT_OF), matching the spatial engine output.
  • NEAR/OVERLAPS are stored once and queried undirected.
  • Derived geometry (centers, width, ...) is not stored; relationships carry no properties.
