feat(coverage): 覆盖图节点用 lucide 图标 + 精简 label + 抽屉展示关联意图/事实

- 节点图标 emoji → 平台一致的 lucide 图标(白色 SVG data URI，iconSrc)
- 图内 label：服务显示 端口·标题·状态码(不再完整 URL)，端点只显示 path
- 点节点抽屉新增「关联意图/关联事实/关联发现」：按 exploration_anchors
  反查本任务锚定该资产的节点
  - db AssetRefs(assetID)；server GET /api/tasks/{id}/asset-refs?asset_id=X
  - types/api taskAssetRefs；抽屉按 node.asset_id 拉取渲染
