Pull request overview

This PR introduces an opt-in switch to embed raw conversation turns on write (so they can be vector-searched), and updates both the SDK and Function App plumbing to support searching either the “memories” container or the “turns” container. It also updates Cosmos container provisioning so the turns container is always created with vector + full-text policies (primed for future turn-search) and standardizes vector index type to quantizedFlat.

Changes:

• Add ENABLE_TURN_EMBEDDINGS / enable_turn_embeddings toggle to control whether turn docs get embeddings on write.
• Add target parameter to search APIs to route vector search to either memories or turns containers.
• Update Cosmos provisioning (SDK + IaC) and tests/docs to reflect always-on turns vector/full-text policies and quantizedFlat vector indexes.
