Build a Coloured Petri Net workflow as a `use ColouredFlow.DSL` Elixir module. Use when the user asks to model concurrent or stateful processes, state machines with event sourcing, business flows that decompose into independently firable steps with shared state, or anything described as a workflow, pipeline with branches, choreography, or saga. Output is a single Elixir module validated at `mix compile`. Skip for purely sequential scripts, one-shot calculations, or flows with no concurrency and no shared state.
