/**
 * Pure dagre auto-layout for the Flow Builder canvas.
 *
 * Mirrors CJO's `getDagreLayout` (`builder/dagreLayout.ts`) — same measured-size-first
 * behaviour and the same dagre-center → React-Flow-top-left coordinate conversion —
 * but consumes this package's own `00`-owned tokens instead of CJO's local literals
 * (`NODE_WIDTH = 240`, `nodesep: 64`, `ranksep: 96`), and runs on the maintained
 * `@dagrejs/dagre` fork rather than the unmaintained `dagre` CJO depends on.
 *
 * Deliberately a pure function, not canvas-internal behaviour: it never mutates
 * `nodes` and the canvas never calls it implicitly. A consumer calls it explicitly
 * (e.g. from an "Auto Layout" button, or a layout-direction toggle) and applies the
 * returned positions to its own controlled `nodes` state — this keeps `<FlowBuilder>`
 * a purely controlled component with no layout side effects of its own.
 *
 * @param nodes - Current nodes. Each node's real rendered size
 *   (`node.measured?.width`/`height`) is preferred; falls back to
 *   `FLOW_NODE_WIDTH`/`FLOW_NODE_MIN_HEIGHT` for anything not yet measured
 *   (first paint, off-screen, freshly added).
 * @param edges - Current edges. An edge whose `source`/`target` is not present in
 *   `nodes` is skipped rather than thrown on.
 * @param direction - Dagre `rankdir`. @default 'LR'
 * @returns A map of node id → top-left `{ x, y }` position, ready to spread onto
 *   each node (`{ ...node, position: positions[node.id] }`). Nodes dagre could not
 *   place (e.g. it failed internally) are simply absent from the map — callers
 *   should fall back to the node's existing position for any id not present.
