Set up comprehensive frontend testing infrastructure

- Install Jest for unit testing with React Testing Library
- Install Playwright for end-to-end testing
- Configure Jest with proper TypeScript support and module mapping
- Create test setup files and utilities for both unit and e2e tests

Components:
* Jest configuration with coverage thresholds
* Playwright configuration with browser automation
* Unit tests for LoginForm, AuthContext, and useSocketIO hook
* E2E tests for authentication, dashboard, and agents workflows
* GitHub Actions workflow for automated testing
* Mock data and API utilities for consistent testing
* Test documentation with best practices

Testing features:
- Unit tests with 70% coverage threshold
- E2E tests with API mocking and user journey testing
- CI/CD integration for automated test runs
- Cross-browser testing support with Playwright
- Authentication system testing end-to-end

+# resolve-cwd [![Build Status](https://travis-ci.org/sindresorhus/resolve-cwd.svg?branch=master)](https://travis-ci.org/sindresorhus/resolve-cwd)
+
+> Resolve the path of a module like [`require.resolve()`](https://nodejs.org/api/globals.html#globals_require_resolve) but from the current working directory
+
+
+## Install
+
+```
+$ npm install resolve-cwd
+```
+
+
+## Usage
+
+```js
+const resolveCwd = require('resolve-cwd');
+
+console.log(__dirname);
+//=> '/Users/sindresorhus/rainbow'
+
+console.log(process.cwd());
+//=> '/Users/sindresorhus/unicorn'
+
+console.log(resolveCwd('./foo'));
+//=> '/Users/sindresorhus/unicorn/foo.js'
+```
+
+
+## API
+
+### resolveCwd(moduleId)
+
+Like `require()`, throws when the module can't be found.
+
+### resolveCwd.silent(moduleId)
+
+Returns `undefined` instead of throwing when the module can't be found.
+
+#### moduleId
+
+Type: `string`
+
+What you would use in `require()`.
