v0.0.18

Tested against DBOS 2.19.0 — see tested_dbos_version in GET /version and dbos-argus --version. Other DBOS versions may still work; the in-app connection indicator surfaces any schema mismatches.

Changed

• Workflow detail flow: child-step Workflow icon, child step name,
  awaited-name in result ← <child>, and the spawn / default-return
  edges all moved off --chart-3 and onto a new
  --workflow-accent token. The token tracks --primary in light
  mode, and in dark mode lifts L to 0.82 and bumps chroma by
  +0.06 via relative-color syntax (oklch(from var(--primary) ...))
  so presets that pick a deep primary (current teal is L=0.437)
  still read as a clear accent against the dark card. Error /
  cancelled return edges keep their --status-error /
  --status-warning strokes.
• Workflow detail flow: ambient gradient gained a third point at
  bottom-left (--color-chart-2, 12% mix), so the canvas reads as
  a balanced three-corner wash instead of a single diagonal sweep.
