* Added support for AMD ROCm net-ib alongside vanilla net-ib, with auto-generation to detect conflicts early during NCCL sync and enable future customizations.
* Integrated AMD AINIC support in RCCL for out-of-the-box usage, leveraging performance improvements by default, channel pinning for optimal pipeline performance, and extended support for 32B in-line CTS messages.
* Implemented internal derivation of AINIC-specific flags when RCCL AINIC environment parameter is set, and checks before initializing AINIC net-ib methods.
* Included snapshot of auto-generated ROCm net-ib file (src/transport/net_ib_rocm.cc) for reference.
* Fixed typos in RCCL param API (RCCL_AINIC_ROCE) and dlclose.
* Updated plugin loading logic:
* Load internal ROCmIB plugin only when NCCL_NET_PLUGIN is not set.
* Load default internal net-ib only when not AINIC and no external plugin env is set.
