Note

Low Risk
Test infrastructure and a non-runtime types re-export split; no production SDK behavior changes.

Overview
Adds browser integration testing for @amplitude/analytics-browser using @web/test-runner with Playwright (Chromium, Firefox, WebKit), esbuild, and Rollup CommonJS for node_modules.

New test:integration script and web-test-runner.config.mjs serve from the monorepo root so pnpm workspace packages resolve. Smoke coverage includes track/identify/flush (smoke.test.ts), DOM click → track (smoke.test.html), and opt-out behavior.

src/types.ts now uses separate export type vs value export blocks from @amplitude/analytics-core (likely to satisfy the browser test bundler). Lockfile picks up the new devDependencies.

Orphaned lockfile package entry

Low Severity

The lockfile gains an importers entry for packages/test-analytics-browser with @esm-bundle/chai and @web/test-runner, but that workspace package does not exist in the repo (only analytics-browser-test does). This looks like leftover state from the web-test-runner experiment.
