test: migrate test suite from Jest to Bun test framework

- Convert test files to use Bun's test framework and mocking utilities
- Update import statements and test syntax
- Add comprehensive test utilities and mock implementations
- Create test migration guide documentation
- Implement helper functions for consistent test setup and teardown
- Add type definitions for improved type safety in tests

+# Migrating Tests from Jest to Bun
+
+This guide provides instructions for migrating test files from Jest to Bun's test framework.
+
+## Table of Contents
+- [Basic Setup](#basic-setup)
+- [Import Changes](#import-changes)
+- [API Changes](#api-changes)
+- [Mocking](#mocking)
+- [Common Patterns](#common-patterns)
+- [Examples](#examples)
+
+## Basic Setup
+
+1. Remove Jest-related dependencies from `package.json`:
+```json
+{
+  "devDependencies": {
+    "@jest/globals": "...",
+    "jest": "...",
+    "ts-jest": "..."
+  }
+}
+```
+
+2. Remove Jest configuration files:
+- `jest.config.js`
+- `jest.setup.js`
+
+3. Update test scripts in `package.json`:
+```json
+{
+  "scripts": {
+    "test": "bun test",
+    "test:watch": "bun test --watch",
+    "test:coverage": "bun test --coverage"
+  }
+}
+```
+
+## Import Changes
+
+### Before (Jest):
+```typescript
+import { jest, describe, it, expect, beforeEach, afterEach } from '@jest/globals';
+```
+
+### After (Bun):
+```typescript
+import { describe, expect, test, beforeEach, afterEach, mock } from "bun:test";
+import type { Mock } from "bun:test";
+```
+
+Note: `it` is replaced with `test` in Bun.
+
+## API Changes
+
+### Test Structure
+```typescript
+// Jest
+describe('Suite', () => {
+  it('should do something', () => {
+    // test
+  });
+});
+
+// Bun
+describe('Suite', () => {
+  test('should do something', () => {
+    // test
+  });
+});
+```
+
+### Assertions
+Most Jest assertions work the same in Bun:
+
+```typescript
+// These work the same in both:
+expect(value).toBe(expected);
+expect(value).toEqual(expected);
+expect(value).toBeDefined();
+expect(value).toBeUndefined();
+expect(value).toBeTruthy();
+expect(value).toBeFalsy();
+expect(array).toContain(item);
+expect(value).toBeInstanceOf(Class);
+expect(spy).toHaveBeenCalled();
+expect(spy).toHaveBeenCalledWith(...args);
+```
+
+## Mocking
+
+### Function Mocking
+
+#### Before (Jest):
+```typescript
+const mockFn = jest.fn();
+mockFn.mockImplementation(() => 'result');
+mockFn.mockResolvedValue('result');
+mockFn.mockRejectedValue(new Error());
+```
+
+#### After (Bun):
+```typescript
+const mockFn = mock(() => 'result');
+const mockAsyncFn = mock(() => Promise.resolve('result'));
+const mockErrorFn = mock(() => Promise.reject(new Error()));
+```
+
+### Module Mocking
+
+#### Before (Jest):
+```typescript
+jest.mock('module-name', () => ({
+  default: jest.fn(),
+  namedExport: jest.fn()
+}));
+```
+
+#### After (Bun):
+```typescript
+// Option 1: Using vi.mock (if available)
+vi.mock('module-name', () => ({
+  default: mock(() => {}),
+  namedExport: mock(() => {})
+}));
+
+// Option 2: Using dynamic imports
+const mockModule = {
+  default: mock(() => {}),
+  namedExport: mock(() => {})
+};
+```
+
+### Mock Reset/Clear
+
+#### Before (Jest):
+```typescript
+jest.clearAllMocks();
+mockFn.mockClear();
+jest.resetModules();
+```
+
+#### After (Bun):
+```typescript
+mockFn.mockReset();
+// or for specific calls
+mockFn.mock.calls = [];
+```
+
+### Spy on Methods
+
+#### Before (Jest):
+```typescript
+jest.spyOn(object, 'method');
+```
+
+#### After (Bun):
+```typescript
+const spy = mock(((...args) => object.method(...args)));
+object.method = spy;
+```
+
+## Common Patterns
+
+### Async Tests
+```typescript
+// Works the same in both Jest and Bun:
+test('async test', async () => {
+  const result = await someAsyncFunction();
+  expect(result).toBe(expected);
+});
+```
+
+### Setup and Teardown
+```typescript
+describe('Suite', () => {
+  beforeEach(() => {
+    // setup
+  });
+
+  afterEach(() => {
+    // cleanup
+  });
+
+  test('test', () => {
+    // test
+  });
+});
+```
+
+### Mocking Fetch
+```typescript
+// Before (Jest)
+global.fetch = jest.fn(() => Promise.resolve(new Response()));
+
+// After (Bun)
+const mockFetch = mock(() => Promise.resolve(new Response()));
+global.fetch = mockFetch as unknown as typeof fetch;
+```
+
+### Mocking WebSocket
+```typescript
+// Create a MockWebSocket class implementing WebSocket interface
+class MockWebSocket implements WebSocket {
+  public static readonly CONNECTING = 0;
+  public static readonly OPEN = 1;
+  public static readonly CLOSING = 2;
+  public static readonly CLOSED = 3;
+
+  public readyState: 0 | 1 | 2 | 3 = MockWebSocket.OPEN;
+  public addEventListener = mock(() => undefined);
+  public removeEventListener = mock(() => undefined);
+  public send = mock(() => undefined);
+  public close = mock(() => undefined);
+  // ... implement other required methods
+}
+
+// Use it in tests
+global.WebSocket = MockWebSocket as unknown as typeof WebSocket;
+```
+
+## Examples
+
+### Basic Test
+```typescript
+import { describe, expect, test } from "bun:test";
+
+describe('formatToolCall', () => {
+  test('should format an object into the correct structure', () => {
+    const testObj = { name: 'test', value: 123 };
+    const result = formatToolCall(testObj);
+
+    expect(result).toEqual({
+      content: [{
+        type: 'text',
+        text: JSON.stringify(testObj, null, 2),
+        isError: false
+      }]
+    });
+  });
+});
+```
+
+### Async Test with Mocking
+```typescript
+import { describe, expect, test, mock } from "bun:test";
+
+describe('API Client', () => {
+  test('should fetch data', async () => {
+    const mockResponse = { data: 'test' };
+    const mockFetch = mock(() => Promise.resolve(new Response(
+      JSON.stringify(mockResponse),
+      { status: 200, headers: new Headers() }
+    )));
+    global.fetch = mockFetch as unknown as typeof fetch;
+
+    const result = await apiClient.getData();
+    expect(result).toEqual(mockResponse);
+  });
+});
+```
+
+### Complex Mocking Example
+```typescript
+import { describe, expect, test, mock } from "bun:test";
+import type { Mock } from "bun:test";
+
+interface MockServices {
+  light: {
+    turn_on: Mock<() => Promise<{ success: boolean }>>;
+    turn_off: Mock<() => Promise<{ success: boolean }>>;
+  };
+}
+
+const mockServices: MockServices = {
+  light: {
+    turn_on: mock(() => Promise.resolve({ success: true })),
+    turn_off: mock(() => Promise.resolve({ success: true }))
+  }
+};
+
+describe('Home Assistant Service', () => {
+  test('should control lights', async () => {
+    const result = await mockServices.light.turn_on();
+    expect(result.success).toBe(true);
+  });
+});
+```
+
+## Best Practices
+
+1. Use TypeScript for better type safety in mocks
+2. Keep mocks as simple as possible
+3. Prefer interface-based mocks over concrete implementations
+4. Use proper type assertions when necessary
+5. Clean up mocks in `afterEach` blocks
+6. Use descriptive test names
+7. Group related tests using `describe` blocks
+
+## Common Issues and Solutions
+
+### Issue: Type Errors with Mocks
+```typescript
+// Solution: Use proper typing with Mock type
+import type { Mock } from "bun:test";
+const mockFn: Mock<() => string> = mock(() => "result");
+```
+
+### Issue: Global Object Mocking
+```typescript
+// Solution: Use type assertions carefully
+global.someGlobal = mockImplementation as unknown as typeof someGlobal;
+```
+
+### Issue: Module Mocking
+```typescript
+// Solution: Use dynamic imports or vi.mock if available
+const mockModule = {
+  default: mock(() => mockImplementation)
+};
+```
