fix: StaticFileManager::registerDirectory() + PSR-12 (release blocker)

[code-cfernandes]

Resumo

Corrige os 2 erros que estavam reprovando a validação de release:

1. PHPStan (Level 9): Application::staticFiles() chamava
   StaticFileManager::registerDirectory($routePrefix, $physicalPath, $this, $options) — mas o
   método foi desacoplado do core (pivotphp/core-routing) e agora espera
   ($routePrefix, $physicalPath, $options). Remove o argumento $this obsoleto.
2. PSR-12: 12 erros de "multi-line function call" em 4 arquivos de teste (auto-corrigidos).

Mudanças

• src/Core/Application.php: staticFiles() corrigido.
• tests/Core/ContainerTest.php, tests/Middleware/SimpleLoadShedderTest.php,
  tests/Middleware/Performance/RateLimitMiddlewareTest.php, tests/Support/StrTest.php:
  formatação PSR-12.

Como testar

composer phpstan          # 0 errors (117 arquivos)
composer cs:check         # 0 errors (8 warnings de linha longa, não-bloqueantes)
composer test:ci
