- Add level-based topological sort (groupNodesByLevel) to identify
nodes that can execute concurrently
- Change state from currentNodeId to currentNodeIds[] for tracking
multiple executing nodes
- Execute nodes in batches using Promise.allSettled with configurable
concurrency limit (default 3, adjustable 1-10)
- Integrate AbortController for fail-fast cancellation on errors
- Pass abort signals to API fetch calls for proper request cancellation
- Update UI: multiple nodes show execution border, FloatingActionBar
shows "N nodes" during parallel execution
- Add concurrency slider in Project Settings > Node Defaults tab
- Store concurrency preference in localStorage
Workflows with independent generate nodes (e.g., 3 parallel image
generations) now complete in ~20-25s instead of ~60-90s sequential.

- Fix global.confirm stub with proper beforeAll/afterAll lifecycle in CostDialog.test.tsx
- Import ReactNode type properly in EdgeToolbar.test.tsx
- Update save-generation route test to expect AbortController signal in fetch call
- Basic rendering with title and handles (image input/output)
