* [Layout] Add IsCompletedReplicated method and enhance layout inference in ParallelOpNode

- Introduced IsCompletedReplicated method in FragmentNode to check if a buffer is fully replicated.
- Enhanced InferLayout in ParallelOpNode to handle layout inference for replicated buffers, ensuring only fragment[0] access is allowed.
- Updated error handling for non-zero index access in fragment buffers to improve robustness.

* [Layout] Improve code formatting and readability in layout.cc and parallel.cc

- Enhanced formatting in FragmentNode's IsCompletedReplicated method for better clarity.
- Updated InferLayout method in ParallelOpNode to improve code readability by adjusting line breaks and indentation.
- Ensured consistent formatting across conditional statements and comments for improved maintainability.
