test(scanner): completar cobertura de ComposerNamespaceResolver
- Criado tests/Unit/Scanner/ComposerNamespaceResolverTest.php com 13 testes: * detectComposerJson: auto-detect via CWD (walk loop exercitado) * loadFromComposerJson: JSON inválido, autoload ausente, arquivo ilegível * extractPsr4Mappings: sintaxe array de dirs, dir inexistente ignorado * includeDevAutoload: true carrega autoload-dev, false ignora * addMapping: dir inexistente ignorado, dir existente registra e resolve * resolve: arquivo inexistente retorna null - Suprimido PHP Warning em file_get_contents com @ operator (L91) O false return já é tratado — o warning é ruído desnecessário Cobertura: 33.33% → 66.67% métodos | 70.83% → 93.75% linhas Linhas restantes (L63, L139): dead branches defensivos não alcançáveis Tests: 215, Assertions: 433 ✓
