// PerfCounterLite.h —— 给 AecRxBase 这类"不链接 CoreLibrary"的模块用的轻量计数器
|

//
|

// 为什么不复用 SectionPerf：CoreLibrary 是静态库且只被 CoreCommand 链接，
|
||||
// AecRxBase.arx 里拿不到它的符号；所以这里做成 header-only。
|
||||
//
|
||||
// 行为：
|
||||
// - 仅在 Debug（NDEBUG 未定义）且 AEC_PERF_COUNTER=1 时开启，Release 零开销
|
||||
// - 每个 tag 统计：调用次数、累计耗时、平均/最长
|
||||
// - 每 200 次调用重写一次 %TEMP%\aec_prim_perf.txt（快照）
|
||||
// —— 故意不写 aec_section_perf.txt：那个文件是自动化脚本判断"开图完成"的信号，
|
||||
// 提前写会让脚本误判并提前关闭 CAD
