- Add help text for add_stage, remove_stage, swap_stages, move_stage commands
- Implement _cmd_add_stage, _cmd_remove_stage, _cmd_swap_stages, _cmd_move_stage methods
- Update _handle_pipeline_mutation in main.py and pipeline_runner.py
- Fix fragile test by testing output buffer directly instead of rendered output
- Add _quit_requested flag to TerminalDisplay
- Add request_quit() method to TerminalDisplay
- Handle 'ctrl_c' key in REPL input loops in both pipeline_runner.py and main.py
- When Ctrl+C is pressed, request_quit() is called which sets the flag
- The main loop checks is_quit_requested() and raises KeyboardInterrupt
Add support for loading pipelines from TOML graph configs in the
pipeline runner, maintaining full backward compatibility with presets.
- Add graph_config parameter to run_pipeline_mode() function
- Support both preset mode and graph mode with conditional logic
- Graph mode: loads from TOML file, uses graph-defined stages
- Preset mode: maintains existing behavior with manual stage building
- Handle items/context appropriately for each mode (graph uses own data sources)
- CLI display flag works in both modes
Backward compatible: graph_config defaults to None, so existing calls
to run_pipeline_mode(preset_name) continue to work unchanged.
