Add resolvePropertyType() helper to extract effective type/format from
OpenAPI wrapper patterns (anyOf, oneOf, allOf, $ref) used by Pydantic
and other code generators. Update isImageInput() and convertSchemaProperty()
to use resolved types instead of reading prop.type directly.
This ensures nullable fields like `{anyOf: [{type: "string"}, {type: "null"}]}`
are correctly identified as image inputs when their name matches image patterns.

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.

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
