fix: remover exclusão padrão de src/Exception no phpunit.xml.dist gerado

- ProjectDetector.php: coverageExclude default alterado de ['src/Exception'] para []
  Projetos que queiram excluir devem declarar explicitamente via coverage_exclude no devkit.php
  A exclusão automática causava PHPUnit Warnings em testes que usam #[CoversClass] em Exception

- PhpUnitConfigGenerator.php: bloco <exclude> agora é condicional via renderExcludeBlock()
  Omite totalmente o bloco quando coverageExclude está vazio → output mais limpo e correto

- PhpUnitConfigGeneratorTest.php: testes atualizados para validar novo comportamento:
  generateOmitsExcludeBlockWhenCoverageExcludeIsEmpty (novo)
  generateContainsCoverageExcludesWhenConfigured (renomeado com contexto explícito)

Quality: cs-fixer ✓ phpstan ✓ psalm ✓ phpunit ✓
