Sorry about this one, Forgot to push after making the change
📝 WalkthroughWalkthroughAfter the pasteFromClipboard operation completes, the code now selects newly created items and invokes two optional lifecycle hooks—onGraphConfigured and onAfterGraphConfigured—on all nodes in the graph to allow post-paste processing. Changes

In `@src/lib/litegraph/src/LGraphCanvas.ts`:
- Around line 4061-4063: created.filter((p) => p instanceof LGraphNode) does not
narrow the resulting array type, leaving createdNodes typed as Positionable[];
change the filtering to use a type predicate so createdNodes is LGraphNode[]
(e.g. replace the predicate passed to created.filter with one that has the
signature (p: Positionable): p is LGraphNode and checks instanceof LGraphNode),
then pass that narrowed createdNodes into forEachNode calls (which call
n.onGraphConfigured and n.onAfterGraphConfigured) so TypeScript recognizes each
element as LGraphNode.

Learning: In the ComfyUI_frontend project, Zod is on v3.x. Do not suggest Zod v4 standalone validators (z.uuid, z.ulid, z.cuid2, z.nanoid) until an upgrade to Zod 4 is performed. When reviewing TypeScript files (e.g., src/platform/remote/comfyui/jobs/jobTypes.ts) validate against Zod 3 capabilities and avoid introducing v4-specific features; flag any proposal to upgrade or incorporate v4-only validators and propose staying with compatible 3.x patterns.

Learning: In the ComfyUI_frontend repository, lint rules require keeping 'import type' statements separate from non-type imports, even if importing from the same module. Do not suggest consolidating them into a single import statement. Ensure type imports remain on their own line (import type { ... } from 'module') and regular imports stay on separate lines.

Learning: Prefer pure function declarations over function expressions (e.g., use function foo() { ... } instead of const foo = () => { ... }) for pure functions in the repository. Function declarations are more functional-leaning, offer better hoisting clarity, and can improve readability and tooling consistency. Apply this guideline across TypeScript files in Comfy-Org/ComfyUI_frontend, including story and UI component code, except where a function expression is semantically required (e.g., callbacks, higher-order functions with closures).

Learning: When accessing reactive properties from Pinia stores in TypeScript files, avoid using .value on direct property access (e.g., useStore().isOverlayExpanded). Pinia auto-wraps refs when accessed directly, returning the primitive value. The .value accessor is only needed when destructuring store properties or when using storeToRefs().

502-512: Guard against missing subgraph on recursion.
forEachNodeassumesnode.subgraphis always defined for subgraph nodes. If that invariant can ever be violated during paste/clone (e.g., subgraph registry not ready), this will throw and break the operation. Please confirm the invariant; if it isn’t guaranteed, add a guard.🛠️ Suggested guard
- if (!node.isSubgraphNode() || visited.has(node.type)) continue + if (!node.isSubgraphNode() || visited.has(node.type) || !node.subgraph) + continue
✏️ Tip: You can disable this entire section by setting review_details to false in your review settings.
This means that the calls are now applied to all nodes, not just new ones, but this is fine

Copying a subgraph which contains primitive nodes would cause the primitives to fail to initialize. This was caused because they did not have their `onGraphConfigured` and `onAfterGraphConfigured` callbacks applied. There's already a copy of `forEachNode` in `@/utils/graphTraversalUtil.ts`, but the method is small and I want to avoid litegraph referencing outside code.
