Module ring_buffer 

Lock-free ring buffer for streaming channels.

This module provides a heap-allocated ring buffer optimized for single-producer single-consumer (SPSC) scenarios with support for MPSC mode via atomic slot claiming.

Design

• Heap-allocated with runtime capacity (unlike const-generic alloc::RingBuffer)
• Power-of-2 capacity with bitmask indexing for fast modulo
• Cache-padded head/tail indices prevent false sharing
• Acquire/Release memory ordering for lock-free operation
• Separate claim_counter for MPSC slot claiming

Performance

Target: < 20ns per push/pop operation in SPSC mode.
