Note

Exposes contentId on the SDK and updates conversion tracking to auto-resolve contentId/variationId (from state/cookies), with React setting contentId during inline renders.

• Core SDK (packages/core):
  • Expose contentId on Builder via contentId$ with get/set accessors.
  • Update trackConversion to:
    • Use stored contentId when not provided.
    • Derive variationId from test cookies when absent.
    • Only include variationId if it differs from contentId.
• React (packages/react):
  • When rendering inline with initialContent, set builder.contentId before tracking impression.
