feat(soe): B9 动作记录 + 时标 SOE（L4-4/L4-5）+ 104 M_SP_TB_1 自发

Browse Source 
- 新增 App/log/soe_rec.{c,h}：64B 定长 SOE 记录纯编解码（CP56Time2a
  时标 + 类型 + 元件号 + 单调序号 + 值 + sum8 撕裂校验），零 I/O 零 OS
  依赖，主机 L0.5 覆盖（32 断言，含与 iec104 CP56 解码器交叉互证）
- 新增 App/log/soe_store.{c,h}：protectTask 边沿投递（取时标 + 组记录 +
  SPSC 待发环/消息队列，零文件系统）；defaultTask 经 syslog_drain 尾部
  排空落 /log/soe.log（卷锁 try / FA_WRITE|FA_OPEN_APPEND / 校验字节数 /
  容量满 unlink 重建，全套照 run.log 实证纪律；无卷损坏归类路径）
- protect_task.c：元件动作/返回、软压板投退、采样闭锁/恢复六类边沿
  → soe_store_post；post 内禁 DBG_*（protect 静态最坏链 872 B 不变，
  改前/改后 stack_report 九任务逐字节一致），丢弃留痕挪 drain 侧
- iec104：单点 YX 自发改 M_SP_TB_1(30) 带 CP56 时标（总召/周期保持
  M_SP_NA_1，单测两种都断言）；link cfg 新增 epoch_ms 时标源回调
  （NULL/无效 → IV 位如实置位）；serv 绑 sys_clock（秒域时基，
  ms 域 = 秒×1000，不造假亚秒）
- 主机单测：test/host/soe/（32 断言）+ iec104 94→97（TB 时标/IV）；
  iec104_master.py 解析 type 30（B6/B7 流不回归）；decode_soe.py
  台架解码断言工具（seq 单调/校验和/UTC 交叉）
- 注册：uvprojx + check_registration SIM_EXEMPT 点名（MCU-only 胶水）
- 文档（我方属主区）：`App/log/README.md` 增 soe 节（64B 记录/单写者/
  post 禁 DBG/UTC 交叉坑）；`docs/子系统设计/IEC104上行设计说明.md`
  §1 范围行 + §3.2 时标注 + §7 台架行 + §8 第 2 条销项 + 变更记录行

台架腿（bench 锁 B9，release --bench-pass）：run_boot_test PASS；
--b7-pre 21/21、--b7-post 13/13（B6/B7 回归 + 确定性动作边沿）；
自发 YX 上送 M_SP_TB_1 带 ts（11:00:51 动作 / 11:00:53 复归）；
FTP 下载 /log/soe.log 30 条记录 decode PASS（seq 0..28 单调、
ELM_ASSERT 14 条、UTC 交叉一致）；定值/压板已恢复默认。

台账 +1088 B（SPSC 环 512 + 静态 FIL 528 + 计数器）随合并由 Lead
回填（ram_baseline --write + check_mem_numbers --write）。

gate: only mem-budget/mem-numbers pending lead ledger backfill
(pre-commit --all-files: 29 Passed / 2 Failed / 0 Skipped;
hygiene self-check OK: no BOM/CRLF/mojibake/trailws/non-ASCII literal)

sync 追平 v2-on-ui（B8 freq + N33 抬栈）后复跑：@build 0/0
（Code=209492 RW=1104 ZI=154184）；stack_report 九任务全 PASS、
protectTask 872 B/57% 不变；ci_local L0.5 15 runner 951/951
（freq 46 / soe 32 / iec104 97 / prot_set 90 / prot_elm 47）。
顺带修 protect_task.c 陈旧注释：定值巡检 31 项 → 40 项（B8 后）。
