Oleg Isonen e4983b0d1d fix: Report unsupported Node versions (#6058)
Closes #6057

## Outcome

Generated projects now reject Node.js versions older than 22.12 before
React Router, Remix, or Vite evaluates SDK components. Users see the
package-manager engine error with the current and required versions
instead of the indirect `sanitize-html` / `htmlparser2`
`ERR_REQUIRE_ESM` stack trace.

## Root cause

`sanitize-html@2.17.6` synchronously loads the ESM-only
`htmlparser2@12`. That dependency combination relies on synchronous
`require(ESM)` support, which Node.js enabled by default in 22.12.
Generated projects incorrectly declared the broader `>=22` range,
allowing an unsupported runtime to reach SSR evaluation.

## Implementation

- Set the CLI and all generated base templates to `engines.node:
>=22.12.0`.
- Add npm `devEngines.runtime` with `onFail: error`, which runs before
install, CI, and run commands.
- Enable `engine-strict` in generated npm configuration so pnpm also
rejects an unsupported runtime.
- Regenerate every tracked CLI fixture package manifest.
- Update CLI documentation and the release-smoke manifest contract.
- Remove the earlier sanitizer-bundling workaround from the branch;
sanitizer code and packaging are unchanged from `main`.

## Checklist

- [x] Declare the exact Node.js compatibility floor
- [x] Fail before generated development, build, and start commands
- [x] Cover the generated engine contract with a fail/pass regression
- [x] Regenerate and inspect all affected fixtures
- [x] Review documentation impact and update the CLI guide
- [x] Keep sanitizer behavior and SDK packaging unchanged

## Verification

- Regression demonstrated failing before the template metadata change
and passing afterward
- `pnpm --filter webstudio test` — 946 passed
- `pnpm --filter webstudio typecheck`
- `pnpm --filter webstudio build`
- `pnpm fixtures`
- `pnpm lint`
- `pnpm exec oxfmt --check` on changed source, template, fixture, and
documentation files
- `git diff --check`

Agent evaluations were not run because they require separate approval.

Webstudio Fixtures

Fixtures are test projects that ensure the CLI and build process work correctly across different deployment targets.

Updating Fixtures After Changes

# From repository root - updates all fixtures
pnpm fixtures

This command will:

  1. Link all fixtures to their respective projects
  2. Sync the latest data from the development environment
  3. Build all fixtures with the latest code

Working with Individual Fixtures

# Go to fixture folder
cd fixtures/webstudio-features

# Link to project
pnpm fixtures:link

# Sync latest data
pnpm fixtures:sync

# Build fixture
pnpm fixtures:build

# Start it
pnpm run dev

Adding Assets to Fixtures

To add a new asset (image, video, audio, etc.) to a fixture:

  1. Publish to staging

    • Make your changes in the builder
    • Publish to the staging environment
  2. Get the build ID from CI

    • After publishing, check the CI logs
    • Find the build ID that was created
  3. Update the fixture's build ID

    • Edit fixtures/[fixture-name]/package.json
    • Update the --buildId parameter in the fixtures:sync script
    "fixtures:sync": "pnpm cli sync --buildId NEW_BUILD_ID_HERE && pnpm oxfmt ./.webstudio/"
    
  4. Sync with the correct environment

    # Go to fixture folder
    cd fixtures/webstudio-features
    
    # Sync from staging environment (replace with your branch)
    BUILDER_HOST=fix-assets.staging.webstudio.is pnpm run fixtures
    
  5. Fix the origin URL

    • After syncing, edit .webstudio/data.json
    • Change the origin back to:
    "origin": "https://main.development.webstudio.is"
    
    • This is necessary because sync changes it to the current branch
  6. Commit the changes

    git add fixtures/
    git commit -m "chore: update fixtures with new assets"
    git push
