…openvinotoolkit#32911) It was observed that the initial implementation of sliding window handling for gpt-oss was incorrect and instead of using the real sliding window value, the 0 stub was always used. * Fix the pattern that captures the real subgraph in the model and extracts the real sliding window value. * Fix the test that was implemented based on the incorrect post-transformation graph. ### Tickets: [CVS-176323](https://jira.devtools.intel.com/browse/CVS-176323) Signed-off-by: Andrii Staikov <[email protected]>
