add-link-object-argument

@codemod/dd-trace-js-v6-add-link-object-argument

Rewrites the Datadog v5 Span.addLink(context, attributes) overload to the v6 single-argument object shape:

span.addLink({ context: otherSpan.context(), attributes: { foo: 'bar' } })

Safety

The transform rewrites .addLink(...) calls with exactly two positional arguments only when the receiver is statically tied to Datadog:

• a direct tracer.scope().active() or tracer.startSpan(...) chain
• a local variable initialized from one of those factories
• a parameter typed as Span imported from dd-trace

Existing object-form calls, unrelated addLink methods, and calls with a different arity are left unchanged.
