resolution in WorkflowCanvas for indexed handles. Add VideoStitch
execution case in regenerateNode.

- 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.

WorkflowCanvas.tsx:
- Import VideoStitchNode
- Add videoStitch to nodeTypes
- Add getNodeHandles case: inputs=["video", "audio"], outputs=["video"]
- Update isValidConnection to allow video→videoStitch connections
- Add minimap color: orange-500 (#f97316)
ConnectionDropMenu.tsx:
- Add videoStitch to VIDEO_TARGET_OPTIONS (first position)
- Add videoStitch to VIDEO_SOURCE_OPTIONS (produces video output)
- Add videoStitch to AUDIO_TARGET_OPTIONS (accepts audio input)
workflowStore.ts:
- Import VideoStitchNodeData type
- Add videoStitch to getSourceOutput (returns video type)
- Add executeWorkflow case for videoStitch with full stitching logic:
* Check encoder support
* Get connected inputs (videos, audio)
* Convert video data URLs to Blobs
* Prepare audio if connected (using prepareAudioAsync)
* Call stitchVideosAsync with progress callback
* Store output (blob URL for >20MB, data URL otherwise)
* Handle errors
Note: nodeDefaults.ts already had videoStitch dimensions and
createDefaultNodeData from Plan 02, so no changes needed there.

The proxy was downloading 80-275MB workflow files through a serverless
function, causing timeouts and failures. Now the proxy just returns the
presigned R2 URL and the client downloads directly from R2.

React Flow's internal bounds for nodes were undefined, causing certain nodes
to be incorrectly included in drag selections regardless of their position.
Added statistical outlier detection using IQR to identify and automatically
deselect nodes that are clearly outside the actual selection area.
Also includes:

- Strip selected property when saving workflows (transient UI state)
- Enable prompt nodes to receive text input connections
