Update Graph Import in session-management.mdx

[mvijil910]

Description

Updating session-management to fix import error. Graph is not exported in multiagent's init and so is not available for import; documentation should be updated to import and use GraphBuilder instead of the Graph class. Reference: [CORRECTION] Documentation is wrong about Graph and SessionManagement #408

Assessment: Request Changes

The import fix is correct — GraphBuilder is the right export from strands.multiagent. However, the rest of the code example (lines 85–91) still uses Graph(...) with a constructor API that doesn't exist, so the example would still fail at runtime.

Review Details

• Completeness: The code example needs to be fully updated to use the GraphBuilder builder pattern (add_node, add_edge, set_entry_point, set_session_manager, build()), consistent with the graph documentation page and the reporter's working example in [CORRECTION] Documentation is wrong about Graph and SessionManagement #408.

Thanks for addressing this issue — the fix is on the right track and just needs the full example updated!
