Fix video element not reloading on regeneration by adding key prop tied
to video history ID. Fix cancel showing timeout message by passing
"user-cancelled" reason through AbortController and checking it in all
three executor catch blocks.

The loopCount (1x/2x/3x) feature was only applied in executeWorkflow()
but not in regenerateNode(), which is the code path triggered by
clicking the "Stitch" button. This adds the blob duplication logic to
both code paths and includes the UI controls and type definitions.

Replace blocking fal.run endpoint with async queue.fal.run + 1s polling
to match Replicate/WaveSpeed behavior. Upload base64 images to fal CDN
before queue submission to avoid large inline payloads. Cache schema
mappings in-memory (30min TTL) to eliminate redundant API calls per
generation. Also fix localStorage cache leaking between tests.

Update stale test mocks from currentNodeId to currentNodeIds in
AudioInputNode, EaseCurveNode, and VideoStitchNode tests. Replace
hard 401 return for missing FAL API key with console.warn, allowing
requests to proceed without auth (rate-limited) since
generateWithFal() already handles null keys gracefully.

handleNodeDragStop used a hardcoded 300x280 fallback for node dimensions,
causing miscalculated centers for non-standard nodes (easeCurve 340x480,
videoStitch 400x280, audioInput 300x200). Now uses the same 3-level
fallback (measured → style → defaultNodeDimensions) as createGroup.

HTML5 drag-and-drop doesn't work inside React Flow nodes because
React Flow captures pointer events at a higher level. Switch to
pointer-event-based reorder with visual feedback (dragged item dims,
hover target highlights with blue ring).

Add nodrag class to thumbnail items so React Flow doesn't capture

All Easing Functions presets were not updating the editor because
handleSelectEasing fell back to the same DEFAULT_CUSTOM_BEZIER for every
non-preset easing. Added EASING_BEZIER_MAP with correct cubic-bezier
values from easings.net and a getEasingBezier() lookup. Also corrected
three PRESET_BEZIERS entries (easeInOutExpo, easeInOutCubic, easeInOutSine)
that diverged from the easings.net source.

Multiple node instances (GenerateImageNode, GenerateVideoNode, etc.) were
each making their own /api/models requests when mounted, causing N duplicate
network requests when N nodes existed on the canvas.
This fix:
- Adds deduplicatedFetch utility that shares in-flight requests to the same URL
- Adds useProviderApiKeys() hook with shallow equality for stable API key refs
- Updates all components to use primitive dependencies instead of object refs
- Uses deduplicatedFetch for all model-fetching operations
Expected result: 1 request instead of N when multiple nodes need the same data.

- Add "video" to Output node's getNodeHandles inputs list
- Consistent with isValidConnection and findCompatibleHandle video->output handling
- Output node now properly accepts VideoStitch connections via all code paths
- Add video handle mapping for videoStitch, generateVideo, and output
- Add audio handle mapping for audioInput and videoStitch

Ensure handles render in all node states (disabled/checking/normal) by
extracting a shared renderHandles function. Move clipOrder syncing from
useMemo side-effect into a proper useEffect. Add dynamic video handle
resolution in WorkflowCanvas for indexed handles. Add VideoStitch
execution case in regenerateNode.
