Terminal UI (TUI) for Grok Build. Provides the interactive full-screen interface
including the scrollback view, prompt input, session management, and all modal
dialogs.

Key Concepts
- AppView — owns the welcome screen, agent sessions, and global config
- AgentView — one per session; owns the prompt, scrollback, tool panes, and modals
- PromptWidget — text editor component with file search (
@), slash commands (/), history search, and paste elements
- Action/Effect — Elm-style architecture: input → Action → dispatch → Effect → state update
