Add Comprehensive Testing Suite

[Patrick-Ehimen]

Add Testing Infrastructure and Test Coverage

Problem

The project currently lacks any testing infrastructure (unit tests, integration tests, e2e tests), which poses risks for:

• Regression bugs during development
• Blog API reliability issues
• Component functionality verification
• SEO metadata validation

Proposed Solution

• Add Vitest for unit/integration testing
• Add Playwright for e2e testing
• Add tests for:
  • Blog API endpoint (server/api/blog.ts)
  • Blog components (components/Blog/)
  • Error handling (error.vue)
  • SEO metadata generation
  • RSS feed parsing logic

Acceptance Criteria

• Unit tests for blog RSS parsing
• Integration tests for blog API
• E2e tests for critical user flows
• CI/CD integration for test runs
• Test coverage reporting
