… span (#762)

* fix: [SVLS-8538] apply durable function tags via setTag on the active span

Tags for aws_lambda.durable_function.* were set through options.tags in
tracer.wrap(), but that path does not reliably reach the aws.lambda span.
Apply them directly via span.setTag() in onEndingInvocation(), the same
way http.status_code is applied.

* feat: [SVLS-8493] add first_invocation tag for durable functions

Tag `aws_lambda.durable_function.first_invocation` is set to "true"
when `InitialExecutionState.Operations` has exactly one entry (first
invocation) and "false" when it has more (replay). Omitted when
InitialExecutionState is absent.

* fix: [SVLS-8583] address code review comments

- Use typeof string guard in extractDurableExecutionStatus for consistency
- Move execution_status tagging outside durableFunctionContext block so it
  applies even when ARN parsing fails
- Add listener.spec.ts tests for execution_status tag being set and not set

datadog-lambda-js ignores upstream trace context propagated via Execution.Input._datadog when a Lambda is invoked from a Step Function, breaking trace continuity for the pattern: upstream Lambda → StartExecution → Step Function → downstream Lambda. This commit extracts datadog headers from Execution.Input._datadog when it is present, linking a lambda span to its upstream step function.
