Ember Browser Navigation Button Test Helper

This package, `ember-cli-browser-navigation-button-test-helper`, provides critical test helpers for simulating browser back and forward button clicks within Ember.js acceptance tests. It exports `setupBrowserNavigationButtons()`, `backButton()`, and `forwardButton()`, enabling developers to thoroughly test navigation flows that involve browser history manipulation. The current stable version is v0.3.0, actively maintained, with releases typically aligning with Ember.js and Ember CLI compatibility updates. Its primary differentiation lies in offering a robust, standardized, and modern Ember-compatible solution for a common testing challenge, where manual DOM manipulation or less integrated approaches might be flaky or difficult to maintain. It specifically targets modern Ember testing paradigms (Ember.js v3.20+ and RFC #232/#268 acceptance tests), ensuring compatibility and best practices.
