Read the option rows with the plugin switched off maybe_upgrade() moved from admin_init to init, so every `wp eval` the e2e helpers make now boots the plugin. That broke the upgrade fixtures twice over: the precondition check that reads the version row was the thing that stamped it, and the eval that writes the legacy row stamped the version first -- so the browser request that was meant to fold the row in returned early and left it behind. The row plumbing now goes through rowEval(), which passes --skip-plugins after the bare `--` wp-env wants. The mu-plugin fixture options and the helpers that need the plugin's own classes keep the plain wpEval. Also opens a test docblock with a capital, which phpcs asks for.
