feat: add topology view mode with router icons and link-style edges

Browse source 
Canvas-global nodeViewMode (bubble/card/topology) can be set at create or via prefs; topology draws NE routers with straight blue center links and exposes router icon to agents.

When the user asks to build a map (e.g. 「输出红楼梦人物关系图」):
1. mindmap_create_canvas({ title: "红楼梦人物关系" }) — ALWAYS creates a NEW canvas id (never overwrites an old one). Opens the right tab on that new canvas.
Topology diagrams: mindmap_create_canvas({ title: "…拓扑", nodeViewMode: "topology" }) then nodes with icon:"router".
2. mindmap_get_spatial_context — orient on the NEW empty canvas
3. mindmap_apply_direct({ ops: [ {type:"batch_create", nodes:[...]}, {type:"auto_fit"} ] })
4. Keep adding in small batches; never dump a full tree JSON overwrite
