[vite-plugin] Backport October 19 SDK release to v1

[petebacondarwin]

Backport the compatible SDK release from #16313 to Vite plugin v1, stacked on #16354 (the separate #16352 runtime backport), above #16334 and #16333. The stack ultimately targets vite-plugin-v1.

Miniflare 5.20261019.0-beta is supplied consistently by #16333 in the plugin, private remote-bindings, and the retained account-id fixture. That earliest necessary backport also supplies coupled Wrangler 4.151.2, runtime-types 0.1.13, workerd 1.20261019.1, and Workers types 5.20261019.1; #16334 supplies containers-shared 0.23.0 and deploy-helpers 0.22.0. All are published and the preceding lockfiles are regenerated. No dependency bump is repeated or reverted here.

Preserve a separate release backport with its own plugin patch changeset and real dev/preview tests importing the built v1 plugin. The tests verify Wrangler configuration parsing, Miniflare startup, Worker bindings, request routing, and generated preview output at the release's compatibility date. V1's changeset workflow generates its release metadata. Private packages and workspace references remain intact; absent public sibling source and v2 release metadata are not restored.

Final validation on Node.js 22.22.1 / pnpm 10.33.0: offline frozen installation, build (3 tasks), all retained unit tasks (8 tasks, 285 plugin tests), and all repository checks (60 tasks) pass. This includes both built-plugin release smoke tests, the installed-runtime regression, and the inline Container dev/preview regressions. Cross-platform CI and maintainer review remain required.

@workers-devprod (recorded release automation author of #16313, account name ANT Bot) and @petebacondarwin (verified human ant-core approver), could you please check this vite-plugin-v1 backport and approve it if it looks good?

This release keeps its own plugin changeset and real built-plugin dev/preview regression tests. Earlier backport #16333 supplies Miniflare 5.20261019.0-beta and its coupled Wrangler, workerd, Workers types, and runtime-types versions; #16334 supplies the Container/deployment helper versions. The dependencies are published and lockfiles regenerated, with build, all unit tests, and repository checks passing locally. Cross-platform CI is running. No v2 release metadata or absent public source is restored.

✅ All checks passed

📋 Code Quality: ✅ LGTM

I found nothing to flag in this change.

• Build ordering: sdk-release.spec.ts imports the built plugin from ../../dist/index.mjs. In the root turbo.json, test and test:ci depend on build, so dist exists when the test runs.
• Test setup: The test uses runInTempDir, writes real files and takes expect from the test context, as the repository's instructions ask. The dev and preview cases each run in their own temporary directory.
• Cleanup: onTestFinished closes the server and restores the stubbed environment variables. Vitest runs these hooks in reverse order, so the cleanup order is correct.
• Changeset: It is a patch changeset for @cloudflare/vite-plugin, which matches the plugin changeset guidance.

📝 Documentation: ✅ LGTM

The changeset accurately describes the backported SDK release. No documentation changes are needed.
