- fal.ts: Use model capabilities to determine fallback content-type
(video/mp4 vs image/png) instead of defaulting to video for all models
- replicate.ts: Increase polling timeout to 10 min for video models;
filter output array to valid strings before URL validation
- nanoBananaExecutor.ts: Replace read-modify-write on outputGallery with
atomic appendOutputGalleryImage using Zustand set() callback

Providers:
- replicate: add SSRF validation on mediaUrl before fetch
- fal/kie/replicate/wavespeed: large-video returns data="" with url set
instead of putting raw URL in data field (violates GenerationOutput.data semantic)
- kie: remove stale WaveSpeed JSDoc block from kie provider file
- route.ts: update all output handling to support data="" + url for large videos
Executors:
- generateVideoExecutor/nanoBananaExecutor: track save-generation fetch in
pendingImageSyncs via new trackSaveGeneration context method so auto-save
waits for server ID resolution
- videoProcessingExecutors: throw errors instead of returning in validation
branches (encoderSupported, insufficient videos, no video connected) so
Promise.allSettled sees rejections
- types.ts: add trackSaveGeneration to NodeExecutionContext interface
- workflowStore: wire trackSaveGeneration into both execution context sites

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.

Remove dead trackSaveGeneration function (no longer called after executor
extraction) and unused type imports. Store: 3,838 -> 1,721 lines (55% reduction).

Wire extracted executors into workflowStore, replacing the ~1000-line
switch statement in executeWorkflow and ~750-line if-else chain in
regenerateNode with executor registry calls. Store reduced from 3,402
to 1,782 lines.

functions. Add 13 new tests.

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.

- Refactor executeSingleNode error paths to throw instead of setting global
isRunning/currentNodeIds state, which corrupted sibling nodes running in
parallel via Promise.allSettled

- Sanitize WaveSpeed taskId in provider with path-traversal validation
- Revoke blob URLs (URL.revokeObjectURL) before replacing outputVideo to
prevent memory leaks from large video files

- AudioInputNode: use named event handlers with removeEventListener in cleanup
- deduplicatedFetch: track setTimeout IDs and clear them in clearFetchCache()
- waitForPendingImageSyncs: clear timeout in finally block after Promise.race

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.

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.

- Create new Blob with correct type for MediaBunny format detection

useMemo side-effect into a proper useEffect. Add dynamic video handle
resolution in WorkflowCanvas for indexed handles. Add VideoStitch
execution case in regenerateNode.

Add applyEditOperations to workflowStore for AI-driven workflow modifications.
Wire ChatPanel to process editWorkflow tool calls and apply operations via store.
Pass lightweight workflow state to chat API for context-aware assistance.
Changes:
- workflowStore: add applyEditOperations method and EditOperation import
- ChatPanel: add onApplyEdits prop, workflowState prop, custom fetch wrapper
- ChatPanel: process tool-invocation parts for editWorkflow and createWorkflow
- ChatPanel: render tool explanations in chat UI
- WorkflowCanvas: extract chatWorkflowState, create handleApplyEdits callback
- WorkflowCanvas: pass onApplyEdits and workflowState to ChatPanel
AI edits trigger captureSnapshot before applying (revert button support).
AI edits do NOT increment manualChangeCount (only manual edits clear snapshot).

loadWorkflow was unconditionally calling clearSnapshot(), wiping the
snapshot that captureSnapshot() just saved. Add preserveSnapshot
option to loadWorkflow and pass it from the AI build workflow path
so the Revert AI Changes button actually appears.
