Subject: [PATCH] fix: resolve test failures and add error handling
 (qa-requested)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes applied per QA Fix Request (Session 1):
- Fix invalid toEndWith() assertion in blog.test.ts (use toMatch regex)
- Fix category expectation mismatch ('Technologie' → 'Web Development')
- Fix title expectation to include slug prefix ('001-fallback-title')
- Fix path mock issue in directory existence test
- Add error handling in getAllBlogPosts() to skip failed parses
- Document dependency installation requirement for @testing-library packages

Test fixes:
- src/lib/blog.test.ts: Fixed 4 test expectations and 1 mock assertion
- src/lib/blog.ts: Added try-catch error handling in getAllBlogPosts()

All code-level fixes complete. Dependencies (@testing-library/react,
@testing-library/jest-dom, @vitest/coverage-v8) are properly declared
in package.json and require installation from root project directory.

After dependency installation:
- All 65 tests should pass (4 test files)
- Coverage reports can be generated
