Track: some flow boards render broken (tangled layout / edges over nodes)

[ivanmkc]

Tracking issue for broken flow-chart rendering.

Some pushed flow boards render hard to read — a tangled layout and/or edges routed over or across nodes. This is the tracker for hardening flow rendering so these lay out cleanly.

Next steps

• Reproduce on an affected board (repro held privately — no environment, workspace, or project details here).
• Investigate the dagre layout params / edge routing and extend the geometry-lint so these cases are caught and laid out readably (cf. prior work in feat(viewer): iOS safe-area insets (viewport-fit=cover) — needs real-device test #131–fix(viewer): readable flow zoom floor on phones (M6) — needs on-device feel check #133).
