Module spsc 

High-performance SPSC Ring Buffer with stack/heap optimization

基于栈/堆优化的高性能 SPSC 环形缓冲区

This implementation uses FixedVec to store data on the stack for small capacities (≤32), avoiding heap allocation overhead and improving new() performance.

此实现使用 FixedVec 在栈上存储小容量数据（≤32），避免堆分配开销，提升 new() 性能。
