Zundo-based undo/redo was causing image flickering, failing to restore
deleted nodes, and creating memory issues from large state snapshots.
Removes the entire workflow undo/redo system while keeping the
independent annotation canvas undo/redo intact.

Replace BINARY_DATA_KEYS (strips all binary) with BINARY_TO_REF mapping
that only strips binary data when a corresponding ref exists (recoverable
from disk). Fields without refs (imageA, imageB, capturedImage, etc.) are
kept in snapshots since they're unrecoverable. After undo/redo, hydrate
missing binary data from refs using existing hydrateWorkflowImages().

VALID_NODE_TYPES was missing audioInput, promptConstructor, outputGallery,
imageCompare, videoStitch, easeCurve, videoTrim, videoFrameGrab, and glbViewer —
all of which are defined in NodeType and have entries in DEFAULT_DIMENSIONS and
createDefaultNodeData. VALID_HANDLE_TYPES was missing video, easeCurve, and 3d
handle types used by EaseCurveNode, GenerateVideoNode, Generate3DNode, GLBViewerNode,
VideoStitchNode, VideoTrimNode, and VideoFrameGrabNode.

- Wrap store creation with temporal() middleware
- partialize: Only track nodes (binary-stripped), edges, edgeStyle, groups
- limit: 20 undo steps max
- equality: Fast referential check using undoStateEquality()
- Add keyboard shortcuts:
- Ctrl/Cmd+Z: Undo last change
- Ctrl/Cmd+Shift+Z: Redo
- Ctrl/Cmd+Y: Redo (Windows alt)
- Add drag debouncing to prevent per-pixel snapshots:
- onNodeDragStart: Pause temporal tracking
- onNodeDragStop: Resume tracking and capture final position
- Add _nudgeForSnapshot() helper to force snapshot capture
- Mark workflow as unsaved after undo/redo
- Install zundo temporal middleware for Zustand
- Create src/store/undoUtils.ts with:
- BINARY_DATA_KEYS: Set of 20+ binary field names to exclude
- stripBinaryData(): Deep-clone nodes without binary data
- partializeForUndo(): Extract trackable state slice
- undoStateEquality(): Fast referential equality check
- UndoState type for type safety
- Replace broad `state.edges` subscription with count-only selector scoped to this
node's target edges, preventing unnecessary re-renders from unrelated edge changes
- Merge two useEffect hooks into one with a null sentinel ref to prevent false
regeneration on mount when loading saved workflows with existing connections
- Pass isExecuting={isRunning} to BaseNode so the Run button grays out during execution
- Update test mock to include edges, regenerateNode, and isRunning

- Output Node now automatically triggers execution when a new connection is made
- Added Run button to Output Node header for manual triggering
- Updated regenerateNode to support output node type
- Prevents re-triggering on initial mount or disconnections using edge count tracking
Resolves issue where Output Node would not display data from already-generated upstream nodes unless connected before generation.

The thumbnail extraction effect had three issues compounding on weak
hardware:
1. The onseeked promise had no timeout — if seek hangs on systems
without hardware video decoding, the entire effect blocks
indefinitely. Added 10-second Promise.race timeout.
2. Created video elements were never cleaned up after use, leaving
phantom decoders running. Added cleanupVideo() that nulls handlers,
clears src, and calls load().
3. The thumbnail cache was cleared wholesale on every run
(thumbnailsRef.current = new Map()), making the cache check on
the next line always miss. Replaced with fingerprint-based
invalidation: only clips whose video data actually changed get
re-extracted, reusing cached thumbnails for unchanged clips.

Data URLs force Chrome to re-parse base64 on each access. With autoPlay
loop, this happens continuously and can freeze the main thread on systems
with weak GPUs that fall back to software video decoding.
Add useVideoBlobUrl hook that converts data URLs to blob URLs via
fetch->blob->createObjectURL. Returns the data URL immediately as
fallback to avoid flicker, then swaps to blob URL once ready (~50ms).
Properly revokes blob URLs on input change and unmount.
Applied to all 6 <video> elements across 5 components:
- GenerateVideoNode (outputVideo)
- VideoStitchNode (outputVideo)
- OutputNode (contentSrc, inline + lightbox)
- EaseCurveNode (outputVideo)
- VideoTrimNode (previewUrl)
Store data is unaffected — getConnectedInputs, executors, and
imageStorage all read outputVideo from the Zustand store, not from
the rendering layer.

getVideoDimensions created a <video> element for dimension detection but
never cleaned it up, leaving a phantom decoder running alongside the
visible video. On systems with weak GPUs (e.g. Intel HD 5500), this
compounds with autoPlay loop to overwhelm Chrome's main thread.
- Add cleanup helper that nulls handlers, clears src, and calls load()
- Add video.preload = "metadata" to avoid fetching full video content
- Add 10-second timeout that cleans up and resolves null if metadata
never loads (graceful degradation: node keeps current size)
- Apply same cleanup pattern to getImageDimensions

Save the previous workflowId and workflowName before mutating state.
If saveToFile() fails, restore the previous values so the workflow
identity is unchanged.

Instead of mutating selectedOutputIndex N times in a loop (which races
with React renders), pass { arrayItemIndex: index } as an edge data
override through onConnect. Adds optional edgeDataOverrides parameter
to onConnect and addEdgeWithType.

Reject patterns with nested quantifiers (e.g. `(a+)+`) that cause
catastrophic backtracking, cap regex input at 100K chars, and add
lime-400 minimap color for array nodes.

The clipKey dependency used a presence-only check ("1"/"0"), so when a
video re-generated (truthy→truthy), the effect never re-ran. Additionally,
the ref-based cache keyed by edgeId returned stale thumbnails even if the
effect did fire. Fix by fingerprinting video data via its trailing 20 chars
and clearing the thumbnail cache when clipKey changes.

The end slider's full-width invisible body (higher z-index) was intercepting
all pointer events, preventing the start slider from receiving input. Fix by
setting pointer-events: none on both range inputs and pointer-events: all on
only the thumb pseudo-elements. Swap z-index so the start handle is on top
when both thumbs overlap at position 0.

When importing a workflow via file picker, loadWorkflow had no way to
find the image files on disk because directoryPath was only stored in
localStorage (which doesn't survive browser switches or clears).
Now auto-save embeds directoryPath in the workflow JSON, and
loadWorkflow uses it as a fallback after the workflowPath parameter
and localStorage config.

Saved workflows can contain multiple edges with the same ID (from
repeated connections or migration normalization). React warns about
duplicate keys and may render edges incorrectly. Deduplicate by
keeping the last occurrence of each edge ID on load.

Saved workflows could contain edges targeting nanoBanana nodes with
indexed handle IDs (image-0, text-0) from a previous schema-based
handle format. GenerateImageNode now always renders non-indexed
handles (image, text), causing React Flow error #008 on every
interaction. Normalize these edge handles during loadWorkflow.

Audio from generateAudio was being silently dropped during video
stitching. Add [VideoStitch] checkpoint logs at each stage where
audio can be discarded: getConnectedInputs, prepareAudioAsync,
and codec detection. Surface codec failure as a visible progress
warning instead of only console.warn.

Switch AVC_LEVEL_4_0 from Baseline profile (avc1.420028) to High profile
(avc1.640028) for broader platform compatibility. Feed audio to the muxer
before video frames so packets are properly interleaved — previously all
audio was dumped after video, causing Discord to skip the audio stream.
Probe total video duration upfront to trim audio to match video length.

The VideoTrim executor was missing from three places:
- execution/index.ts barrel export
- workflowStore.ts regenerateNode if-else chain
- workflowStore.ts executeSelectedNodes switch
This caused the Trim button to complete instantly with no processing
and no video output downstream.
