**Date:** 2025-11-22  
**Version:** 0.1.7  
**Tasks:** TASK-004_Modeling_Tools

## 🚀 Key Changes

### MCP Server (Client Side)
- Added `IModelingTool` interface in **Domain** layer.
- Implemented `ModelingToolHandler` in **Application** layer.
- Registered new MCP tools in **Adapters** layer:
  - `create_primitive(type, size, location, rotation)`: Creates Cube, Sphere, Cylinder, etc.
  - `transform_object(name, location, rotation, scale)`: Moves/rotates/scales an object.
  - `add_modifier(name, type, properties)`: Adds modifiers (e.g., Subsurf).

### Blender Addon (Server Side)
- Implemented `ModelingHandler` in `blender_addon/application/handlers/modeling.py`.
- `create_primitive` logic supports types: Cube, Sphere, Cylinder, Plane, Cone, Torus, Monkey.
- Registered new RPC handlers in `blender_addon/__init__.py`.

### Testing
- Created `tests/test_modeling_tools.py` with full coverage (mocks).

AI has gained the ability to create and modify geometry in Blender.
