[WIP] Add package-lock.json for deterministic dependency installation

[Copilot]

• Investigate CI failure (job 72305068973 - "Responsive Layout Tests" failing on npm ci due to missing package-lock.json)
• Update package.json to include @playwright/test@^1.59.1 devDependency and scripts
• Generate package-lock.json by running npm install
• Commit and push both files

Original prompt

The CI workflow is failing because npm ci requires a package-lock.json file to exist in the repository. Currently, the project has package.json but is missing the lock file.

Error from job 72305068973:

The `npm ci` command can only install with an existing package-lock.json or
npm-shrinkwrap.json with lockfileVersion >= 1.

Solution:
Generate and commit a package-lock.json file that locks the dependencies defined in package.json:

• dependencies: chess.js@^0.10.3
• devDependencies: @playwright/test@^1.59.1

This will ensure deterministic dependency installation in CI environments and allow the GitHub Actions workflow to proceed successfully.

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: Please find a solution for failing job 72305068973. Use the logs, job definition, and any referenced files where the failure occurred. Keep your response focused on the solution and include code suggestions when appropriate.

Assistant: I'll help you find a solution for the failing job. Let me start by getting the logs for that job.

Assistant: Now let me check the repository to see if there's a package-lock.json file:

Assistant: ## Solution for Failing Job 72305068973

The job failed because package-lock.json is missing from the repository. The npm ci command on line 46 of .github/workflows/deploy.yml requires a package-lock.json or npm-shrinkwrap.json file to work.

Root Cause

The error message indicates:

The `npm ci` command can only install with an existing package-lock.json or
npm-shrinkwrap.json with lockfileVersion >= 1.

Your package.json exists but there's no corresponding lock file to ensure deterministic dependency installation in CI environments.

Solution

Add package-lock.json to your repository:

1. Locally, run:

   npm install

   This will generate a package-lock.json file that locks your dependencies to specific versions.

2. Commit and push the generated package-lock.json file to your repository:

   git add package-lock.json
   git commit -m "Add package-lock.json for deterministic installs"
   git push

Once package-lock.json is committed to the repository, the npm ci command in your CI workflow will succeed, and the Playwright tests will run properly.

Why This Matters

• npm ci (clean install) is safer for CI/CD because it installs exact versions from the lock file
• npm install is used locally and can update versions; it creates the lock file
• The lock file ensures everyone uses the same dependency versions, preventing version-related issues

User: commit a package-lock.json for this project

Assistant: I'll create a package-lock.json file for your project based on the package.json and commit it to the repository.

Assistant: Done! I've initiated the creation of a pull request to add package-lock.json to your repository. The PR will generate a lock file based on your current package.json dependencies (chess.js and @playwright/test) and commit it to ensure your CI workflow can run npm ci successfully.
