v1.1.0

1.1.0

This release delivers major improvements in AI Gateway and LLM integration, including a full-featured LLM proxy, token billing, retry/fallback strategies, and HTTP/SSE streaming support.
The gateway and ingress architecture has been significantly refactored, with redesigned routing and a modernized application gateway model for cloud-native environments.
Model Context Protocol (MCP) support is introduced, enabling standardized AI service integration with registry and authorization capabilities.
Service governance and observability are enhanced through deeper Nacos integration, dynamic configuration, unified metrics, and improved health checks.
Numerous refactors, cleanups, and CI/build upgrades improve overall stability, maintainability, and long-term evolution.
