Expose Native Google Ads Criterion ID for Keywords

Please expose the native Google Ads keyword criterion ID together with the Zernio keyword ID in keyword read and mutation responses.

We need a stable documented mapping such as:

keywordId
platformCriterionId
campaignId
adSetId
resourceName

Google Ads reporting through GAQL identifies keywords using the native criterion ID, while Zernio keyword mutation endpoints currently require the Zernio keyword ID.

Without a deterministic mapping between these identifiers, it is not safe to reconcile keyword performance data with keyword update, pause, enable or delete operations.

This mapping would enable reliable keyword lifecycle management and read-after-write verification.
