Gives the general chat a createRecipe tool (Vercel AI SDK, stepCountIs(3)) scoped so it can only ever produce a draft — the tool's execute is a pure echo, no DB write. The route surfaces the tool call as proposedRecipe alongside the normal text answer; the chat UI renders it as a card with explicit Create/Discard buttons. Create POSTs to the existing /api/v1/recipes endpoint — the same code path and tier/recipe-count limit the manual editor already goes through — so there's exactly one place that actually creates a recipe row, and nothing happens without the user clicking Create. Scoped to the general assistant only (not per-recipe chat), and to one tool for now — addToShoppingList/generateMealPlan are follow-ups. v0.45.0
