Changelog

This release upgrades the base OSS version from v1.4.11 to v1.4.12, bringing a full-featured prompt repository with RBAC, large payload optimization, WebSocket-based responses API, Anthropic passthrough, session stickiness, and a unified pricing engine. On the enterprise side, this release adds KV store gossip protocol support, RBAC for the prompt repository, and build/deployment improvements.
