CLI: Full-Screen Diagram Viewer and Sign-In to More MCP Servers

This release adds a full-screen viewer for Mermaid diagrams that are too wide for your terminal, and signs you in to more MCP servers with no OAuth configuration. It also lets you run one more iteration or finish a workflow loop that used all its iterations, tells you when workflows are not available in autonomous mode, asks before a V2 shell command sets XDGCONFIGHOME or HOME, and fixes file search, custom agent, workflow, spec, Hook, clipboard, help text, and session issues.
