Review Comment:
I think that since we make this introduction here, it would be good to
describe use cases. This just tells the reader they can do it maybe but doesn't
explain much about what it would be used for and when you should and shouldn't
reach for it..
> Enable multiple label support on vertex with configurable label cardinality
> ---------------------------------------------------------------------------
>
> Key: TINKERPOP-3261
> URL: https://issues.apache.org/jira/browse/TINKERPOP-3261
> Project: TinkerPop
> Issue Type: Task
> Affects Versions: 4.0.0
> Reporter: Yang Xia
> Priority: Major
>
> Vertices are currently limited to a single immutable label assigned at
> creation. This prevents modeling common real-world scenarios where entities
> naturally belong to multiple categories (e.g., a person who is both an
> employee and a manager).
>
> Introduce a configurable LabelCardinality that controls how many labels a
> vertex may have and whether they can be mutated after creation. Three
> proposed modes: ONE (current behavior, default), ONE_OR_MORE (mutable,
> minimum one), ZERO_OR_MORE (fully flexible).
>
> New steps:
>
> - labels() — flatMap step emitting each label as a traverser
> - addLabel(String, String...) — add labels to a vertex
> - dropLabel(String, String...) — remove specific labels
> - dropLabels() — remove all labels
> Edge labels remain at cardinality ONE. The infrastructure would support
> future edge multi-label enablement without wire format changes.
