Восстановление preview-мешей перед обновлением контекста при undo/redo

[SashaRX]

Motivation

• Исправить баг, когда обработчик OnUndoRedo напрямую вызывал ctx.Refresh(...) пока в сцене стояли временные preview-меши, из‑за чего временные sharedMesh могли закешироваться как исходные и привести к утечке/порче ссылок на импортированный меш.

Description

• В Editor/Framework/UvToolHub.cs перед вызовом ctx.Refresh(...) добавлены вызовы ApplyPreviewMode(UvCanvasView.PreviewMode.Off) и RestoreWorkingMeshes(), что отключает активные превью и восстанавливает/удаляет временные рабочие меши до перестроения MeshEntries.

Testing

• Запущены автоматические проверки: git diff --check и статическая проверка порядка вызовов (подтверждающая, что ApplyPreviewMode → RestoreWorkingMeshes выполняются до ctx.Refresh), обе проверки прошли; EditMode Unity-тесты не запускались в этой среде, так как бинарник Unity отсутствует.

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in: 45 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
