Canvas AI assistant

A chat panel next to the canvas lets you prompt changes in plain language and watch the workflow build and update side by side.

The biggest piece of v4: an AI assistant docked beside the canvas, not a separate generator you run once and hand off from. Describe what you want in plain language, and watch it draft, wire, and adjust nodes on the canvas as you go, in a running conversation rather than a one-shot plan.

Early beta points:

Prompt to add, remove, or rewire nodes without leaving the canvas
Explanations stay grounded in the actual graph in front of you, not a generic answer
Works alongside manual editing — take over a step it just added any time, and it picks up from there
