Fix static analysis errors in Ray.Di type system

- Fix array offset access in Bind.php with null coalescing operator
- Update Container.php with proper return type annotations and suppress mixed return
- Refine ParameterNameMapping type to allow empty string keys for Name::ANY
- Add missing type imports and improve parameter handling in Name.php
- Update Arguments.php return type annotation to list<mixed>
- Clean up AssistedInjectInterceptor type annotations
- Remove redundant psalm-assert annotation from DependencyInterface
- Configure PHPStan raw error format for better CI integration
