Adds an alternative display mode where processes run directly in tmux windows instead of the built-in TUI. tmux handles terminal emulation, scrollback, and display while numux remains the orchestrator. - Add Runner interface and RunnerFactory to decouple ProcessManager from ProcessRunner - Add TmuxRunner that manages processes inside tmux windows using pipe-pane for output monitoring and exit sentinel files - Add TmuxDisplay that creates a tmux session with status-icon window names and attaches to it - Generalize setupShutdownHandlers to accept ShutdownTarget interface Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
