juanatsap 8a709c6863 improve: Add type safety, middleware, and comprehensive handler tests
Five complementary improvements to handler layer:

1. Fix Pre-Commit Hook
   - Remove broken Perl-style regex (unsupported by Go)
   - Use -short flag to exclude integration tests
   - Tests now run successfully in pre-commit

2. Extract Duplicate Logic
   - Remove 100+ lines of duplicate data preparation
   - Both Home() and CVContent() now use prepareTemplateData()
   - Reduce cv_pages.go from 290 to 120 lines (58% reduction)

3. Request/Response Types
   - Create internal/handlers/types.go with structured types
   - PDFExportRequest, LanguageRequest, PreferenceToggleRequest
   - Type-safe parameter parsing with centralized validation
   - Refactor ExportPDF to use typed requests

4. Middleware Extraction
   - Create internal/middleware/preferences.go
   - PreferencesMiddleware reads cookies once, stores in context
   - Automatic migration of old preference values
   - Ready for integration in routes

5. Handler Tests
   - Add internal/handlers/cv_pages_test.go (190 lines, 15+ cases)
   - Add internal/handlers/cv_htmx_test.go (325 lines, 20+ cases)
   - Test language validation, toggles, cookies, methods
   - Increase handler test coverage significantly

Testing:
- All unit tests pass (35+ new test cases)
- Pre-commit hook working
- Build succeeds
- No breaking changes

Benefits:
- Type safety: Compile-time parameter validation
- Code quality: 170 lines of duplication eliminated
- Testing: 100% increase in test files
- Architecture: Clean middleware pattern
- Developer experience: Self-documenting request types

Documentation:
- Create _go-learning/refactorings/004-handler-improvements.md
- Document all five improvements with examples
- Include metrics, testing strategy, and future improvements
