- Fix raw mode enabling to not duplicate with UI border mode
- Add REPL_USAGE.md with comprehensive guide
- Add examples/repl_demo_terminal.py example script
- Detect REPL effect in pipeline and enable interactive mode
- Enable raw terminal mode for REPL input capture
- Add keyboard input loop for REPL commands
- Add _handle_pipeline_mutation() function for pipeline control
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.
