TreeMetricsTrait
Defines the property name constants of the structural tree metrics carried by {@see \xyz\oihana\schema\thesaurus\traits\HasTreeMetrics}.
Centralizing these keys avoids hardcoded string literals and provides a single source of truth for hydration and serialization.
It is aggregated, through ThesaurusTrait,
into the global Oihana constants class, so
the field is reachable via Oihana::CHILDREN_COUNT.
Typical usage:
$term[ TreeMetricsTrait::CHILDREN_COUNT ] = 8 ;
