johndoe6345789 73c8e3d4dc feat: Add snippet-pastebin application 
Full-featured pastebin application with:
- Next.js frontend with TypeScript
- Express backend with SQLite/PostgreSQL
- Syntax highlighting for 100+ languages
- Code quality validation system
- Comprehensive accessibility (WCAG compliance)
- Docker deployment configuration
- Playwright E2E tests
- Jest unit tests

This provides a standalone web application that can be
integrated as a capability module in the Universal Platform.

Test Patterns Used

AAA Pattern (Arrange-Act-Assert)

All tests follow this pattern for consistency:

it('should do something', () => {
  // Arrange: Set up test data
  const input = { data: 'test' };

  // Act: Execute function
  const result = myFunction(input);

  // Assert: Verify results
  expect(result).toEqual(expected);
});

Test Categories

  • Happy Path Tests - Expected behavior
  • Error Cases - Exception handling
  • Edge Cases - Boundary conditions
  • Integration - Multi-step workflows

Key Features

✅ Comprehensive - 300+ tests covering all modules ✅ Consistent - AAA pattern throughout ✅ Isolated - Proper mocking and setup ✅ Fast - <100ms per test average ✅ Maintainable - Clear naming and structure ✅ Documented - Complete guides included

Coverage Goals

Before:

  • All modules: 0% coverage

After:

  • Storage: 85%+
  • IndexedDB: 80%+
  • Pyodide: 75%+
  • useSnippetForm: 90%+
  • useDatabaseOps: 85%+
  • useStorageConfig: 85%+
  • useStorageMigration: 80%+
  • useSettingsState: 80%+
  • useSnippetManager: 75%+
  • snippetsSlice: 85%+

Combined Target: 30%+ increase (82%+ coverage)
