* [refactor] Improve renderer architecture organization
Building on PR #5388, this refines the renderer domain structure:
**Key improvements:**
- Group all transform utilities in `transform/` subdirectory for better cohesion
- Move canvas state to dedicated `renderer/core/canvas/` domain
- Consolidate coordinate system logic (TransformPane, useTransformState, sync utilities)
**File organization:**
- `renderer/core/canvas/canvasStore.ts` (was `stores/graphStore.ts`)
- `renderer/core/layout/transform/` contains all coordinate system utilities
- Transform sync utilities co-located with core transform logic
This creates clearer domain boundaries and groups related functionality
while building on the foundation established in PR #5388.
