cu_tuimon

cu_tuimon is the shared Ratatui UI library for Copper monitors.

It does not implement CuMonitor itself. Instead, it provides:

• MonitorModel: shared monitor state updated from Copper runtime data
• MonitorUi: reusable Ratatui rendering for system info, DAG, latency, bandwidth, pool, and log views
• MonitorUiEvent and MonitorUiKey: backend-neutral monitor input events shared by multiple frontends
• MonitorLogCapture: shared live Copper log and optional stderr capture for monitor frontends
• shared scrolling and screen-selection behavior used by multiple frontends

Current intended consumers:

• cu_consolemon: terminal / crossterm frontend
• cu_bevymon: Bevy / bevy_ratatui frontend

Input ownership:

• cu_tuimon owns monitor behavior and bindings
• cu_tuimon owns the shared LOG pane, including live Copper log formatting
• frontend adapters translate raw backend events into MonitorUiEvent
• cu_tuimon never needs to know whether it is running in a terminal or in Bevy

This crate lives under components/libs because it is a reusable UI backend, not a standalone monitor component.
