Workflow playground

Building a workflow used to mean writing DOT by hand. The new /playground page lets you build one by describing it: chat with Ask Fabro on the right while a live canvas re-renders the workflow graph on the left. The canvas supports pan, zoom, fit-to-window, click-to-inspect node details, and a Play button that walks through the graph so you can sanity-check the flow before running anything. When you’re happy with it, download the workflow as a .fabro.zip — including workflow.fabro, workflow.toml, and a README — or use Run for real to create an actual run and jump straight to its run page.
