Avoid wp-env silent startup failures when loading Plugin Check

[Copilot]

plugin-check-action was generating a .wp-env.json that always loaded plugin-check from a download URL. On newer GitHub runner images, that URL-plugin path can cause wp-env to exit successfully without actually initializing the environment, leading to Environment not initialized. Run \wp-env start` first.` in later steps.

• Remove the fragile URL-plugin bootstrap path

  • Stop adding https://downloads.wordpress.org/plugin/plugin-check.zip to the generated .wp-env.json.
  • Keep the generated config focused on core version, ports, and the checked plugin mapping.

• Install Plugin Check after wp-env is up

  • Install and activate plugin-check via WP-CLI after wp-env start.
  • Reuse an existing install when present, activating it instead of reinstalling.

• Fail early if wp-env did not actually start

  • Extend the retry-wrapped startup command to run wp-env run cli wp cli info immediately after wp-env start --update.
  • This turns silent startup failures into explicit failures that the retry step can catch.

• Add focused regression coverage

  • Add a test that asserts the action no longer references plugin-check.zip.
  • Add a test that asserts startup now includes a post-boot verification command.

command: |
  wp-env start --update
  wp-env run cli wp cli info

Pull request overview

This PR updates the composite action to avoid wp-env “silent success” startup failures caused by preloading Plugin Check via a remote ZIP URL, and instead installs/activates Plugin Check after the environment is confirmed running.

Changes:

• Removes https://downloads.wordpress.org/plugin/plugin-check.zip from the generated .wp-env.json.
• Extends the retry-wrapped wp-env startup to immediately verify the environment with wp-env run cli wp cli info.
• Installs (or reuses and activates) the plugin-check plugin via WP-CLI after wp-env is up, and adds regression tests validating these behaviors.
