Vertex AI Vector Search: validate embedding dimensions and distance measure at deploy time

[googlecloudplatform/cloud-networking-solutions]: validate embedding dimensions and distance measure types when creating the index. Distance measure types are DOTPRODUCTDISTANCE, COSINEDISTANCE, and L2SQUARED_DISTANCE; shard sizes come in SMALL, MEDIUM, and LARGE. Recommended models: gemini-embedding-001 at 768 dimensions. Also verify the Vertex AI API is enabled in the project, and monitor index creation and deployment logs: a failed deployment is usually the API, the network and firewall settings, or the dimension config, in that order.

Context: Dimension and distance-measure mismatches between the index config and the embedding model surface as failed deployments or wrong results.
