…onForEviction This commit renames the Python function CloseSession to MarkSessionDefunct to better reflect its actual behavior and align with the C++ API. The function marks a session as temporarily defunct when there's a suspected loss of synchronization with the peer, but allows the session to become active again if messages are received. Additionally, adds a new function MarkSessionForEviction that permanently marks a session for removal by detaching all SessionHolders and releasing references, which will deallocate the session if no references remain. Once marked for eviction, the session can never become active again. Both functions have been properly documented to explain their behavior, parameters, and differences. All references to CloseSession throughout the codebase have been updated to use MarkSessionDefunct.
