FigJam adds agent-driven planning and new MCP diagramming tools

FigJam has introduced new MCP skills that allow AI coding agents to directly read and write on FigJam boards, enabling collaborative technical planning with human engineers. Extensions to the generate_diagram tool now support complex architecture and ERD layouts, making it easier to visualize system designs. New workflow skills like generate-project-plan also automate the creation of interactive visual boards from technical documents and codebases.
