"""Update workspace task status on the canvas.

Usage (from any script, cron job, or shell inside the container):

  # Set current task (shows on canvas card)
  python3 -m molecule_runtime.molecule_ai_status "Running weekly SEO audit..."

  # Clear task (removes banner from canvas)
  python3 -m molecule_runtime.molecule_ai_status ""

The status appears as an amber banner on the workspace card in the canvas,
visible to the project owner in real-time.
