fix: release graph_runtime_state reference to prevent memory leak 

Release the _graph_runtime_state reference in stop_listen() to allow
Python GC to reclaim memory immediately after request completion.

Without this fix, the reference chain:
  AppQueueManager._graph_runtime_state -> GraphRuntimeState -> Graph -> Node -> graph_runtime_state
prevents garbage collection until the entire pipeline object is released,
causing memory to accumulate under high concurrency.

Fixes #30183
