- Enhanced the iteration logic for managing copy stage dependencies, ensuring accurate identification of producer stages.
- Added safeguards against exceeding maximum iterations during dependency propagation.

* Implement new free stage layout inference.

* Fix bug

* Make replication upcasting and unnormalizable iterators safe.

* Better handling of updating with more replica

* Remove unnecessary check.

* Fix compilation.

* Fix setup.py.

* Simplify development mode.

* Allow ParallelOp layout when there's already a compatible layout specified

* lint fix

* Add ProveFragmentContains function to validate thread access between small and large fragments

This function checks if the threads accessing elements of a smaller fragment are a subset of those accessing a larger fragment, ensuring valid access during updates. The implementation includes deriving thread indices, computing logical indices, and verifying thread mappings.

* Update dependencies in requirements files

* Remove 'thefuzz' from requirements-dev.txt
* Specify exact versions for 'torch' and add 'flash_attn' in requirements-test.txt

* Update CI workflow to use SHA256 hash for requirements file

* Update requirements and CI workflow for flash attention

* Removed specific version for 'torch' in requirements-test.txt
* Added installation of 'flash_attn==2.5.8' in CI workflow to ensure compatibility

* Refactor flash attention import handling in examples

* Removed availability checks for 'flash_attn' in multiple example scripts.
* Simplified import statements for 'flash_attn' to ensure consistent usage across examples.
