feat: Add multi-environment browser testing with real API integration
- Add browser environment test suite (jsdom) * Import validation tests * Initialization tests with real .env credentials * Dependency safety checks (catches fs/path/crypto usage) * Real API call tests using existing .env - Add bundle validation scripts * validate-browser-safe.js: Scans bundles for Node.js-only APIs * test-bundlers.js: Validates bundler compatibility - Add test configurations * jest.config.browser.ts: Browser environment Jest config * jest.setup.browser.ts: Browser test setup * playwright.config.ts: Real browser testing (structure) - Update package.json with new npm scripts * test:browser: Run browser environment tests * test:all: Run all tests (unit + api + browser) * validate:browser: Validate bundle safety * validate:bundlers: Test bundler compatibility - Update .gitignore * Add .env to prevent credential leaks * Adjust docs/ pattern This implements AWS SDK v3-style multi-environment testing to catch Node.js-only API usage (fs, path, crypto) before production, preventing customer build failures in browser environments.
