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

+# dequal [![CI](https://github.com/lukeed/dequal/workflows/CI/badge.svg)](https://github.com/lukeed/dequal/actions)
+
+> A tiny (304B to 489B) utility to check for deep equality
+
+This module supports comparison of all types, including `Function`, `RegExp`, `Date`, `Set`, `Map`, `TypedArray`s, `DataView`, `null`, `undefined`, and `NaN` values. Complex values (eg, Objects, Arrays, Sets, Maps, etc) are traversed recursively.
+
+> **Important:**
+> * key order **within Objects** does not matter
+> * value order **within Arrays** _does_ matter
+> * values **within Sets and Maps** use value equality
+> * keys **within Maps** use value equality
+
+
+## Install
+
+```
+$ npm install --save dequal
+```
+

+
+## Usage
+
+```js
+import { dequal } from 'dequal';
+
+dequal(1, 1); //=> true
+dequal({}, {}); //=> true
+dequal('foo', 'foo'); //=> true
+dequal([1, 2, 3], [1, 2, 3]); //=> true
+dequal(dequal, dequal); //=> true
+dequal(/foo/, /foo/); //=> true
+dequal(null, null); //=> true
+dequal(NaN, NaN); //=> true
+dequal([], []); //=> true
+dequal(
+  [{ a:1 }, [{ b:{ c:[1] } }]],
+  [{ a:1 }, [{ b:{ c:[1] } }]]
+); //=> true
+
+dequal(1, '1'); //=> false
+dequal(null, undefined); //=> false
+dequal({ a:1, b:[2,3] }, { a:1, b:[2,5] }); //=> false
+dequal(/foo/i, /bar/g); //=> false
+```
+
+## API
+
+### dequal(foo, bar)
+Returns: `Boolean`
+
+Both `foo` and `bar` can be of any type.<br>
+A `Boolean` is returned indicating if the two were deeply equal.
+
+
+## Benchmarks
+
+> Running Node v10.13.0
+
+The benchmarks can be found in the [`/bench`](/bench) directory. They are separated into two categories:
+
+* `basic` – compares an object comprised of `String`, `Number`, `Date`, `Array`, and `Object` values.
+* `complex` – like `basic`, but adds `RegExp`, `Map`, `Set`, and `Uint8Array` values.
+
+> **Note:** Only candidates that pass validation step(s) are listed. <br>For example, `fast-deep-equal/es6` handles `Set` and `Map` values, but uses _referential equality_ while those listed use _value equality_.
