Support for nested composites in field setup - composites can now contain other composites.

Example structure:

Product Specifications
├── Dimensions
│   ├── Width
│   ├── Height
│   └── Depth
└── Materials
    ├── Primary
    └── Secondary

Features:

• Configurable depth - Prevent runaway complexity per storage

• Expandable tree view - Focus on specific levels

• Validation at each level - Data quality throughout structure

Essential for rich product attributes and complex content models. Value Composer handles nested composites seamlessly.
