Phase 5 batch: door + window migrate to registry (always-on)

Both kinds share traits — hosted on walls, cuttable, animated open/
close state via a geometry system + animation system. Stage A
migration: register + wrap-export the legacy renderer + bundle both
per-kind systems. Pure geometry + floor-plan ports are later
milestones.

Files added (packages/nodes/src/door/, packages/nodes/src/window/):
 - schema.ts: re-export from core.
 - parametrics.ts: minimal — dimensions only. Door has 29 sliders +
   segmented controls + presets in its legacy panel; window has 15+
   sliders. Auto-inspector can't cover them at Stage A — legacy
   panel keeps rendering via panel-manager.tsx case fall-through.
   Stage E may extend parametrics or use parametrics.customPanel
   escape hatch.
 - definition.ts: capabilities (no `movable` — wall-bound drag is
   bespoke; capability-driven dispatch keeps legacy MoveDoorTool /
   MoveWindowTool), parametrics, renderer, system. defaults() uses
   `DoorNode.parse({...stub})` to leverage zod's schema-level
   `.default()` annotations — door has 40+ fields, window has 20+;
   listing them inline duplicates the schema.
 - renderer.tsx: wrap-export of legacy DoorRenderer / WindowRenderer
   (thin 33-36 lines each).
 - system.tsx: bundles each kind's TWO systems — DoorSystem +
   DoorAnimationSystem, WindowSystem + WindowAnimationSystem. Both
   per-kind systems mount via RegisteredSystems when the kind is
   registry-driven; `<LegacySystem kind="door|window">` wrappers
   around each individual system short-circuit.
 - index.ts: barrel.

Files changed:
 - packages/viewer/src/index.ts: new public exports for DoorRenderer,
   DoorSystem, DoorAnimationSystem, WindowRenderer, WindowSystem,
   WindowAnimationSystem.
 - packages/nodes/src/index.ts: appends doorDefinition + windowDefinition.
 - packages/editor/src/components/ui/panels/door-panel.tsx + window-
   panel.tsx: panel slider-drag fix recipe applied. Drop the
   subscribed `updateNode` action, drop the `node` dep from
   handleUpdate / previewDoorUpdate / commitDoorPreview useCallbacks.
   Use useScene.getState() inside. Door panel has 29 SliderControls,
   window 15+ — both at high risk of the Maximum update depth
   cascade without the fix.

Phase 5 progress: shelf ✅, spawn ✅, wall ✅, fence ✅, slab ✅, ceiling ✅,
door ✅, window ✅. Eight kinds on the registry. Item / stair / roof /
zone / containers remain.
