[Proposal] Add Visualization Marker Abstraction (Axes, Primitives, etc.) #129
Description
Proposal
Introduce an abstraction layer for visualization markers within EmbodiChain. This should include:
- Axis markers (e.g., coordinate axes for spatial reference)
- Primitive shapes (e.g., cubes, spheres, cylinders) that support customizable color materials and alpha (transparency) channel
- Flexible support for additional marker types for future extensibility
- Unified interface for marker creation, modification, and rendering

Motivation
Clear visualization is vital for understanding spatial relationships, debugging, and developing features in distributed, robotic, or blockchain-based environments. By abstracting marker types (axes, primitives, materials, alpha), developers and users can:
- Render spatial information in a consistent, modular way
- Easily extend marker types for new visualization demands
- Use transparency (alpha) to overlay multiple data sources
- Connect and visualize data from core blockchain nodes in 3D/2D scenes
This feature targets developer experience and usability, enabling rapid prototyping and richer visual feedback.
Additional context
Consider marker extensibility and registration for custom types. Review ROS Marker interface, Unity/Unreal Engine marker/Gizmo systems, and Three.js scene graph for inspiration.
