Add Goals and Todos page; link from sidebar, Graph Runtime, Examples Document the per-thread goal (graph::goals) and task board (graph::todos) primitives in depth: data models, Store-backed persistence, the harness tool surfaces, and the graph-native continuation (goal_gate_node self-driving loop, run_continuation_tick driver, note_user_turn). Add a Graph Runtime section and an Examples entry for the goals_and_todos example, and link the new page from the sidebar.
