v0.2.1 — edge rendering fixes
Three fixes to the run flowchart's edges:
- Edges below the fold no longer vanish. The SVG overlay holding the edges was sized to the visible canvas rather than the full scrollable graph, so on tall workflows every edge past your window height was drawn but clipped.
- Arrowheads are filled triangles instead of stroked chevrons that looked misaligned at small sizes.
- Branch fan-in gets one arrowhead. Edges converging on the same node used to stack their arrowheads at the same point; converging edges now meet at a junction above the node and enter it with a single shared arrowhead, colored by whether the inbound path was taken.
