Run Playwright tests on BrowserStack's cloud grid for cross-browser and cross-device testing.
Environment variables must be set:
BROWSERSTACK_USERNAME — your BrowserStack usernameBROWSERSTACK_ACCESS_KEY — your access keyIf not set, inform the user how to get them from browserstack.com/accounts/settings and stop.

pw-browserstackwas removed from the plugin's.mcp.jsonbecause it failed to connect for every user (the plugin ships nonode_modules).
