This massive update aligns the codebase with our PRD by adding kernel authentication primitives (including secure session handling and rate limiting), a full-featured MCP server with templated resources and prompts, and a redesigned A2A layer with background task scheduling. We also upgraded the CLI to v1.0.2 to support these new capabilities, ensuring everything is anchored by 65 new tests. Everything is now much more robust, secure, and ready for production workflows.
