lemurclaw-tui 0.0.1

//! Canonical TUI session state shared across app-server routing, chat display, and status UI.
//!
//! The app-server API is the boundary for session lifecycle events. Once those responses enter
//! TUI, this module holds the small internal state shape used by app orchestration and widgets.
