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.

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.

- 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.

The aspectRatio, resolution, and useGoogleSearch controls were only
shown when isGeminiOnly was true, but that was always false since
fal.ai is always available. Now these controls show based on whether
the currently selected model is a Gemini model.

Fixes issues with external provider models (e.g., seedream-4.5) where:
- Boolean/integer params with "image" in name were misclassified as image inputs
- Array params without items.type specification were incorrectly rejected
- Handle ID mismatch between node components (image-0) and store (image)
- dynamicInputs not passed to API in node regeneration code path
Changes:
- Update isImageInput() to check schema types, not just names
- Map both indexed (image-0) and legacy (image) handle IDs to schema names
- Add dynamicInputs to nanoBanana regeneration request body
- Add hidden backward-compat handles for edge routing
- Add comprehensive tests for schema classification and handle mapping
- Fix Toast test to use specific selector for close button

- Update findCompatibleHandle to return normalized IDs
- Map normalized handles to schema names in getConnectedInputs
- Exclude image_size from image input detection
- Switch save-generation to hash suffix format for better readability
Co-Authored-By: Claude <noreply@anthropic.com>

matching, preventing num_images from being misclassified as image input

nanoBanana and generateVideo nodes
- Update fal.ai schema fetch to use Model Search API endpoint

- Introduced a model search dialog for selecting external models in GenerateImageNode and GenerateVideoNode.
- Updated node titles to reflect selected models dynamically.
- Improved parameter handling by expanding the ModelParameters component to notify parent nodes on schema load.
- Adjusted handle positions and styles for better alignment and visual consistency.
- Enhanced input validation and processing for dynamic inputs across the workflow.
Use calc() to offset handle positions by 5px (half of 10px handle size)
to center handles at their percentage positions. This ensures edge
connection points align with the visible handle dots and labels.
Avoid using CSS transform which breaks React Flow's handle detection.
