Replace 4 hardcoded pipeline methods (_run_expert_pipeline, _run_director_pipeline, _run_thinker_pipeline + dispatch logic) with a single _walk_edges() method that follows declared data edges. Key changes: - _WalkCtx dataclass carries state through the edge walk - _eval_condition() evaluates conditions against walk context - _resolve_edge() picks active edge (conditional > unconditional) - Dispatch adapters per node role (_dispatch_pa, _dispatch_expert, etc.) - PA retry + progress wrapping stay as expert dispatch adapter logic - process_message() and _handle_action() use _walk_edges() - _run_reflex() kept as simple 2-frame shortcut 15/15 engine tests + 9/9 matrix tests green, identical traces.
