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
