Resolve three issues with the Conditional Switch node:
- Add fromHandleType resolution for conditionalSwitch in handleConnectEnd so
the connection drop menu appears when dragging from rule/default outputs
- Align output handles with visual rule rows by accounting for the text preview
height in baseOffset and using fixed h-8 rows matching handleSpacing=32
- Move "Add Rule" button after the Default row so the default handle aligns
with its visual row instead of being displaced

Nano Banana Pro supports 1K/2K/4K, while Nano Banana 2 also supports 512.
Split the shared RESOLUTIONS constant into RESOLUTIONS_PRO and RESOLUTIONS_NB2,
and use the correct list based on the selected model in both GenerateImageNode
and SplitGridSettingsModal. Also normalize aspect ratio and resolution to valid
defaults when switching models in the SplitGrid modal.

Nano Banana 2 (gemini-3.1-flash-image) supports a new searchTypes API
that allows enabling web search and image search independently. This adds
a useImageSearch toggle visible only for Nano Banana 2, while keeping the
existing Google Search toggle using the legacy format for Nano Banana Pro.

Make aspect ratio dropdowns model-aware: nano-banana-2 shows 14 ratios
while other models keep showing the base 10. Also add nano-banana-2 to
the SplitGrid settings model list.

The menu path calls onConnect() directly, bypassing handleConnect's
resolveSwitchHandle. This left edges with targetHandle "generic-input"
instead of the actual type, causing inputType to be invalid, handles
to render without color, and downstream connections to fail validation.
- Set targetHandleId to actual type in handleMenuSelect Switch case
- Update Switch inputType immediately when created from menu
- Filter "generic-input" in derivedInputType as safety net

Switch output handles use dynamic IDs (random strings) that getHandleType()
can't resolve. Now falls back to the Switch node's inputType field so dragging
from a Switch output shows the correct type-specific connection menu.

Zundo-based undo/redo was causing image flickering, failing to restore

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().

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.

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.
