rusteron-rb vs ringbuf vs shm-primitives

Provides ring buffer and broadcast functionalities via aeron c bindings, allowing efficient, low-latency message passing between different threads or processes. This module implements Single Producer, Single Consumer (SPSC) ring buffers, Multi-Producer, Single Consumer (MPSC) ring buffers, and broadcast channels.

Lock-free SPSC FIFO ring buffer with direct access to inner data

Lock-free primitives for shared memory IPC: BipBuffer, slot metadata, and OS-level doorbell/mmap
