The merge logic in setOutputsByLocatorId updated app.nodeOutputs but returned early without updating nodeOutputs.value, so Vue components never received merged output updates.

Not sure if it'd work, but you might be able to do satisfies Partial<ComfyApp> instead of the type assertions.

## Summary Fix for COM-14110: Preview image does not display new outputs in vue-nodes. ## Problem The merge logic in `setOutputsByLocatorId` updated `app.nodeOutputs` but returned early without updating the reactive `nodeOutputs.value` ref. This caused Vue components to never receive merged output updates because only the non-reactive `app.nodeOutputs` was being updated. ## Solution Added `nodeOutputs.value[nodeLocatorId] = existingOutput` after the merge loop, before the return statement. ## Testing - Added 2 unit tests covering the merge behavior - All 4076 existing unit tests pass - Typechecks pass - Lint passes ## Notes - Related open PRs touching same files: #8143, #8366 - potential minor conflicts possible Fixes COM-14110 ┆Issue is synchronized with this [Notion page](https://www.notion.so/PR-8479-fix-update-reactive-ref-after-merge-in-imagePreviewStore-2f86d73d365081f1a145fa5a9782515f) by [Unito](https://www.unito.io) Co-authored-by: Amp <amp@ampcode.com>
