Change fillScreen from lipgloss.Left to lipgloss.Center for horizontal positioning so content is centered based on actual terminal dimensions. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Replace monolithic internal/termapp with proper separation: - internal/app: App struct, lifecycle, output loops - internal/command: CommandHost interface, Dispatcher, handlers - internal/tui: Model, hotkeys, panels, render (with panelError + border fixes) - internal/console: RunConsole, escape parsing, entry point logic - cmd/serialterminal: thin main() calling console.Run() Eliminate global vars (cfg, sess, out) via dependency injection. Break App->CommandDispatcher cycle via CommandHost interface. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
