Code Review

This pull request updates the @web/test-runner-puppeteer dependency to version ^1.0.0 along with its lockfile. The review feedback recommends upgrading all core @web/test-runner packages to ^1.0.0 simultaneously to prevent version mismatches, potential runtime conflicts, and lockfile bloat.

[gemini-code-assist]

Updating only @web/test-runner-puppeteer to ^1.0.0 while keeping @web/test-runner and @web/test-runner-core on older versions (^0.20.2 and ^0.13.4 respectively) leads to duplicate and mismatched versions of @web/test-runner-core and @web/test-runner-chrome in the dependency tree (as seen in the pnpm-lock.yaml changes). To prevent potential runtime issues, plugin registration conflicts, and bloated lockfiles, all core @web/test-runner packages should be upgraded to ^1.0.0 together.
