feat(V4B): V4.23 — 红灯呼吸对齐vd960Loop(≈2.6s) + 上电自检基准判稳

Browse Source 
现场测试 DLD154V4 反馈两问题修复:

1. 红灯呼吸太快 → 借鉴 vd960Loop 效果 (main.c poll_red_pwm)
   - 参数按 665/6800 缩放取整: 大步 100→39(≈5.9%), 近顶 20→10(≈1.5%),
     分界 585(88%), 峰值保持 660×3 步
   - 周期 ≈1.6s → ≈2.6s (仿真 42 步×60ms=2520ms)

2. 绿灯上电自检闪到"稳定基准值"才停 (TaskLoop.c 稳定期判稳)
   - 根因: 固定 128 样本即判稳, 与基准是否稳定无关; static 计数不清零,
     二次稳定期(安全复位)1 样本瞬间判稳
   - 修复: 全局 g_stable_cnt/g_settle_cnt, 每窗(100样本≈1s)Origin 均值
     漂移 ≤0.1% → settle++, 连续 2 窗 + 最少 128 样本判稳; 硬兜底 500
     样本(5s); 计数判稳退出/INIT_VD 清零

验证: tests/test_power_on_stable.c (200/300/500/200 样本 PASS),
      tests/test_red_breath.c (周期 2520ms/峰值保持/写值≤ARR PASS),
      gcc -fsyntax-only 两文件 0 error (借 vd960Loop AT32F421 库头)
文档: devlog 置顶 + 修订表回填 V2.12~V2.20 + V2.21; product-manual §5.1/
      核心特性; technical-spec V2.2 (§5.2 参数表/§7 判稳语义/§15 修订记录)

待现场验证: 呼吸观感、绿灯自检时长 (无车 2~3s / 首窗尖峰 3s / 5s 兜底)

/*
* test_power_on_stable.c — 上电自检: 基准值稳定后才结束自检 (V4.23)
*
* 背景: 原逻辑 _stable_cnt 达 128 样本(≈1.3s)即判稳, 与"基准值是否真稳定"无关;
* 且 static 计数不清零, 二次稳定期(安全复位)1 个样本即判稳(绿灯自检形同虚设)。
* 修复: 稳定期累计样本 g_stable_cnt + 连续窗口 Origin 均值漂移 ≤0.1% 的
* g_settle_cnt; 两者达标才 g_loop_stable=1; 硬兜底 500 样本(5s)。
*
* 验证:
* 1. 干净常量值 → 第 200 样本判稳 (窗口100/200 两次漂移 0)
* 2. 首窗 Origin 尖峰(1.3×) → 多等一窗, 第 300 样本判稳
* 3. 持续漂移(每窗 +500, >0.1% 带) → 永不 settle, 第 500 样本硬兜底判稳
* 4. 判稳退出后计数清零, 二次稳定期重新从 0 累计(不瞬间判稳)
*
* 编译: gcc -Wall -o test_power_on_stable test_power_on_stable.c && ./test_power_on_stable
