Adds the floor-plan side of the three-checkbox composition model documented in wiki/architecture/node-definitions.md. Mirrors the 3D side (def.geometry → <GeometrySystem> → <ParametricNodeRenderer>) but emits SVG primitives instead of three.js Object3Ds, and runs inside the floor-plan panel. Type-side (packages/core/src/registry/types.ts): - New FloorplanGeometry tagged union covering path / polygon / polyline / rect / circle / line / group. FloorplanStyle props map straight to SVG attributes. Coordinates are level-local meters; rotations are radians (three.js convention). - New `def.floorplan?: (node, ctx) => FloorplanGeometry | null` field on NodeDefinition, independent of `geometry` and `renderer`. Re- exported via packages/core/src/registry/index.ts. Runtime (packages/editor): - <FloorplanGeometryRenderer> walks the FloorplanGeometry tree and emits the matching React-SVG elements. Pure data → DOM; no per-kind logic. - <FloorplanRegistryLayer> reads the active levelId, walks the level subtree, looks up each node's def.floorplan, builds a GeometryContext, calls the builder, and renders the output via FloorplanGeometryRenderer. - Mounted in floorplan-panel.tsx just before <FloorplanMarqueeLayer> so registry-driven kinds layer above legacy inline content. Shelf migration (proof port): - New nodes/src/shelf/floorplan.ts — buildShelfFloorplan(node) emits a group with the rotation/translation transform and a width × depth rectangle in the shelf's color. Brackets omitted (hidden under top board from above). - Wired to shelfDefinition.floorplan. Shelf now appears in the floor plan view for the first time (was missing from the legacy panel's inline switch). Pattern proven; every future kind migrating in Phase 5 follows the same shape: a pure (node, ctx) => FloorplanGeometry function. As kinds register their floor-plan builders, the corresponding inline branches in floorplan-panel.tsx become dead code and can be deleted in the same PR.
