Cancel now waits for the compositor job to settle, deletes a partial GIF, and keeps an existing destination so the dialog can retry the same path without stale progress.

In `@src/components/ai-edition/ExportDialog.tsx`:
- Around line 287-293: Update handleCancel’s cancelGifExportNative rejection
path to reset cancellation state and explicitly surface the failure through the
dialog’s error-toast flow, rather than leaving phase as rendering where
ProgressBlock hides the error. Preserve the existing native-settlement handling
so { accepted: false } is treated as a race won by export completion, allowing
the successful result to be shown.

A rejected cancel IPC left the dialog on the rendering phase, so progress stayed visible and hid the error. Move to the error phase and toast the message without changing the accepted-false race.

Summary
Cancelling a GIF export now waits for native work to settle, removes partial output, and preserves an existing destination. The export options stay available for a same-path retry, and progress from an older job cannot update the new job.

Type of change
Release impact
Desktop impact
The shared native export and Electron bridge change. Hardware validation was performed on Windows; macOS/Linux hardware behavior is not claimed.
Screenshots / video
The change affects export cancellation rather than layout. The checked-in manual E2E log records the Windows cancel, cleanup, and same-path retry sequence; private capture media is not attached.
Testing
Targeted tests cover job ownership, cancellation cleanup, and bridge/client wiring:
npx vitest --run electron/ipc/gifExportJobs.test.ts src/components/ai-edition/ExportDialog.cancel.test.tsx electron/native-bridge/services/compositorViewService.test.ts src/native/compositorViewClient.test.tsThe GIF Playwright spec covers cancel and retry wiring:
npx playwright test tests/e2e/gif-export.spec.ts.Fork CI on this head passed lint, application/test TypeScript checks, the unit suite, the build, and Windows compositor checks.
Real Windows OS input cancelled a GIF during frame rendering and retried the same path. Native output cleanup was verified and the completed GIF decoded successfully. Existing-destination preservation is also covered by native-addon tests.
Known limits
GIF frame-delay quantization at 15 FPS is unchanged. This is a scoped export-cancellation fix, not a release-packaging or full cross-platform manual pass.
