Cypress Netlify Build Plugin

The `netlify-plugin-cypress` package integrates Cypress end-to-end testing directly into the Netlify build pipeline. It allows developers to run Cypress tests against their deployed site (default), or earlier in the build process (preBuild, postBuild) to prevent broken deployments. The current stable version is 2.2.1, with recent updates in February 2023. This plugin differentiates itself by automating the setup and execution of Cypress within the Netlify environment, including automatically installing a Chromium browser via Puppeteer, and providing options to control when tests run relative to the deployment lifecycle. It is primarily configured via `netlify.toml`, offering a declarative way to incorporate E2E testing into continuous deployment workflows.
