Represents the degree of connection between two people in a social network.
**DEFINITION**:
ConnectionDegree captures the "distance" in a social network graph:
- **1st degree**: Direct mutual connection
- **2nd degree**: One person between viewer and connection
- **3rd+ degree**: Two or more people between
**IMPORTANT**: The degree is relative to the VIEWER (person conducting
the search), NOT the target profile being analyzed. See AGENTS.md Rule 17.
**SEMANTIC PATTERN**:
```

└── has_degree → ConnectionDegree (THIS CLASS)
└── has_type → ConnectionDegreeType (FIRST, SECOND, THIRD_PLUS)
```
**MIGRATION NOTE** (Rule 53, 2026-01-22):
Created as part of connection_degree migration. Wraps the simple enum
in a structured class for consistency with other Type/Types patterns.
