Vertex AI Vector Search: list()/get_all fails on non-768-dimension indexes
Complete solution
Vertex AI Vector Search: list()/get_all fails on non-768-dimension indexes: : the mem0 Vertex AI Vector Search integration builds the zero query vector with a hardcoded dimension of 768 and the config has no dimension field, so any index with a different dimension (OpenAI 1536/3072) rejects the query.

Instructions
[mem0ai/mem0#6419]: the mem0 Vertex AI Vector Search integration builds the zero query vector with a hardcoded dimension of 768 and the config has no dimension field, so any index with a different dimension (OpenAI 1536/3072) rejects the query. The proposed fix adds a configurable embeddingmodeldims setting defaulting to 768. Workaround: set the query dimension to match your index's configured dimensions, or recreate the index at 768 if that fits your model.
Context: Mem0 GoogleMatchingEngine list(), getall and deleteall fail for indexes whose embedding dimension is not 768, because the zero query vector is hardcoded to 768 dimensions.
