refactor: use Uri.file().fsPath for spawn args, fix inline type imports

- Replace phpUnitProject() with Uri.file(phpUnitProject()).fsPath in
  expectSpawnCalled args to match production code behavior on Windows
- Keep only cwd comparison case-insensitive (drive letter ambiguity)
- Replace inline import('../../PHPUnit').TestSuiteFinished with proper
  top-level type imports in CollisionPrinter and OutputFormatter tests
