Task 605: DAG Viewer WASM Feature Integration

Status: DONE

Summary

Task 604 ported DAG analysis to Rust/WASM and exposed 11 functions. The browser DAG viewer currently uses 5 of them (layout, impact, analyze, upstream, downstream). This task integrates the remaining 6 functions into the viewer UI:

1. dag_validate — Show validation warnings/errors in a panel
2. dag_stale_nodes — Highlight stale nodes with visual indicator
3. dag_find_paths — Path-finding between two selected nodes
4. dag_summarize — Summary statistics panel (node counts by type/status)
5. dag_subgraph — Tag-based subgraph filtering with depth control
6. dag_task_planning — Task readiness info (plannable/blocked/parallel groups)

Dependencies

• Task 604 (DONE) — DAG Rust/WASM port
