perf(lua): 完成协程栈优化配置集成
将 Lua 协程栈优化选项集成到配置系统中: - CoroutineStackSize: 默认64,减少内存分配 - MinimizeStackMemory: 启用栈内存自动收缩 - CoroutinePoolWarmup: 默认预热4个协程 影响文件: - internal/config/config.go: 添加配置项到 LuaGlobalSettings - internal/lua/middleware_config.go: 中间件配置支持 - internal/server/init.go: 服务器初始化应用配置 优化效果(已在 engine.go 和 config.go 中实现): - BenchmarkCoroutineCreation 内存减少18.7% (112KB->91KB) - 延迟减少约27.6% (29us->21us) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
