Replace 6 duplicated header-building if/else chains (across executeWorkflow
and regenerateNode) with buildGenerateHeaders() and buildLlmHeaders() utility
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.

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.

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

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

Two related issues fixed:
1. Image history IDs not syncing before workflow save (PR#27 follow-up):
- Added pending sync tracking for save-generation API calls
- saveToFile() now awaits all pending syncs before saving
- Ensures imageHistory/videoHistory IDs match actual saved filenames
2. Duplicate images created on every save:
- After externalization, store nodes now receive the image refs
- Subsequent saves recognize existing refs and skip creating new files
- Prevents inputs/ and generations/ folders from accumulating duplicates
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The save-generation API changed to use prompt+hash based filenames for
deduplication, but the workflow store was still using timestamp-based IDs
in imageHistory/videoHistory. This caused the carousel to fail loading
images since the IDs didn't match the actual saved filenames.
Now we capture the API response and update the history entry with the
actual imageId returned by the save-generation endpoint. This is backward
compatible - old workflows with timestamp-based filenames continue to work.
