## Summary
- Adds Playwright E2E tests for the Node Library V2 sidebar tab
(`Comfy.NodeLibrary.NewDesign: true`)
- Adds `NodeLibrarySidebarTabV2` fixture class with V2-specific locators
(search input, tab buttons, node cards)
- Exposes `menu.nodeLibraryTabV2` on `ComfyPage` for test access
- Tests cover: tab visibility, default tab selection, tab switching,
folder expansion, search filtering, and sort button presence
## Test plan
- [ ] Run `pnpm test:browser:local -- --grep "Node library sidebar V2"`
against a running ComfyUI server with the V2 node library
- [ ] Verify tests pass in CI
