Run the Browserbase VM e2e with source ~/misc/env.txt && pnpm --dir packages/core exec vitest run tests/browserbase-e2e.test.ts. The test aliases BROWSER_BASE_API_KEY and BROWSER_BASE_PROJECT_ID from ~/misc/env.txt to the BROWSERBASE_* names the CLI expects, projects the Browserbase CLI packages into the VM through moduleAccessCwd, creates/releases the remote session from inside the VM with a tiny guest fetch() helper, and drives navigation plus screenshot capture through browse --ws <connectUrl> while direct guest egress to unrelated domains stays denied.
