feat: add tests

Description

Adds browser-based Vitest suites (Playwright: Chromium, Firefox, WebKit) for @web3auth/no-modal and @web3auth/modal, with tests living under each package’s test/ folder.

• Vitest config (test/configs/browsers.config.mts): loadEnv("test", <packageRoot>, "VITE_") plus define for process.env.VITE_APP_INFURA_PROJECT_KEY so dependencies that read Infura env at load time work in the browser.
• Setup (test/setup/browser-polyfills.ts): ensures globalThis.process exists so SDK / dependency code that touches process.env (e.g. WEB3AUTH_VERSION) does not throw in the browser runner.
• Coverage: Istanbul against each package’s src/**/*.{ts,tsx} as appropriate.
• Modal: server.fs.allow for the monorepo root (hoisted node_modules) and optimizeDeps.include for React/UI-related deps to avoid mid-run Vite reloads and flaky dynamic imports in browser mode.
• ESLint: relax import/no-extraneous-dependencies for packages/**/test/**; modal package eslint targets ./test/configs/browsers.config.mts for devDependency resolution.
• .env.test.example in each package documents optional VITE_APP_INFURA_PROJECT_KEY for local .env.test.

no-modal tests cover Web3AuthNoModal, BaseConnector, and shared helpers/mocks. Modal tests cover Web3Auth (modal manager) and LoginModal UI (mount/open).

How has this been tested?

• cd packages/no-modal && npm test — Vitest browser run (3 browsers) with coverage; all tests passing.
• cd packages/modal && npm test — same; all tests passing.
• Root: npm test (Lerna parallel test in workspaces) should run both package test scripts.

Screenshots (if appropriate)

N/A — test and tooling changes only; no end-user UI product changes.

Note

Medium Risk
Mostly adds test infrastructure and new browser-run test suites, but it also changes how tests are executed (removes node configs / per-package scripts) and introduces a new dependency plus a large package-lock.json churn that could affect CI installs.

Overview
Adds browser-based Vitest (Playwright) test coverage for @web3auth/no-modal and @web3auth/modal, including new test/ helpers/mocks and suites that exercise key connector/Web3Auth flows plus a basic LoginModal UI mount/open check.

Updates Vitest browser configs to load VITE_ env via Vite, inject VITE_APP_INFURA_PROJECT_KEY, allow monorepo-root FS access, and (for modal) pre-bundle heavy UI deps to reduce flakiness; coverage reporting is expanded and test-only files are excluded.

Aligns tooling around the new test layout by relaxing ESLint’s import/no-extraneous-dependencies for packages/**/test/**, simplifying root and package test scripts to run the browser config, adding .env.test.example files, and updating dependencies/lockfile (including adding ox).
