…rward abort was previously fanned out from master httpserver to slave httpservers over zmq so every node's local shm got is_aborted=True before the router's MIN-allreduce agreed. now rank 0 is the single source of truth: the router broadcast(src=0)s the aborted_req_mask and slaves write is_aborted back to their local shm so recycle_resource_loop still observes a consistent state. side effects: - disable_abort gate is removed; is_disconnected -> abort now works in multinode tp dp=1 mode. - PortLocker no longer locks nccl_port on slave ranks (only rank 0 binds the TCPStore listener), which fixes single-machine multi-node tp testing. adds test/test_api/test_abort_chaos.py covering abort_all on N concurrent streams and random per-stream disconnect chaos.
