dot

Add a complete new flow to `dot` — a `flows/<name>.go` file with its full question graph, a `Generators` resolver, registration in `flows/registry.go`, every new generator the flow needs (delegating to `dot-add-generator`), every new question (delegating to `dot-add-question`), and a full set of `tools/test-flow/testdata/` fixtures. Trigger when the user says "add a flow", "new flow", "ajoute un flow", "create a scaffold for X", or describes a brand-new wizard that doesn't fit any existing flow.

Add a new generator package to the `dot` scaffolding tool — creates the generator.go + manifest.go + files/, registers it in `internal/cli/registry.go`, writes the doc in `docs/contributor/generators/`, and updates affected sibling generators when scope overlaps. Trigger when the user says "add a generator", "create a generator", "new generator", "ajoute un générateur", or describes a chunk of project scaffolding that doesn't yet exist as a generator.

Add a question (TextQuestion, ConfirmQuestion, OptionQuestion, LoopQuestion, IfQuestion) to a `dot` flow — wires the node into the graph, updates the flow's `Generators` resolver, asks whether any existing generators need to react to the new branch, and extends the matching `tools/test-flow/testdata/` fixtures. Trigger when the user says "add a question", "ajoute une question", "new flow question", or describes a new choice the wizard should offer.
