* [Feature] Add FullyReplicated Fragment Layout and Enhance Layout Inference

* Introduced a new static method `FullyReplicated` in the `Fragment` class to create fully replicated fragment layouts, ensuring all threads hold identical copies of the buffer.
* Updated `CopyNode` to collect fragment layouts and mark them as fully replicated during layout inference.
* Enhanced `ParallelOpNode` to expand let bindings for fragment buffer accesses, improving layout inference accuracy.
* Added documentation for new methods and updated existing methods to support the new layout features.

* lint fix

* Remove debug logging statements from layout inference process to streamline output and improve performance.
