CLI 新增 disp 数码管显示值命令 (APP V1.00.32)

- disp <value> [f] [hex]: 设置 7 段数码管显示数值
  - 默认十进制 1 位小数 °C; f 点亮 °F 指示段; hex 按十六进制整数显示
- 手写 cli_parse_float/cli_parse_hex (不依赖 MicroLIB atof/strtod)
- 背景: 数码管 display_task 之前无任何任务调用 display_set(), 一直显示静态 0
- 仅 APP 改动, Boot 不动 (仍 V1.00.07)
- docs/开发日志.md: 新增 §60

+## 60. CLI 新增 `disp` 数码管显示值设置命令（2026-09-06，APP V1.00.32，仅 APP）
+
+- 背景：§58 的数码管驱动只有 `display_task` 扫描，全局值
+  `g_disp_value/g_disp_type/g_disp_base` 初值 0.0/°C/十进制，**全程无任何
+  任务调用 `display_set()`**（链接 map 显示 `i.display_set` 被裁掉），
+  数码管一直显示静态的"0"（小数点常亮）。本次加 `disp` 命令提供修改入口。
+- 实现（`mcm-ddc-ble/src/cli_core.c`，仅 APP）：
+  - `cli_parse_float()`：手写十进制浮点解析（符号/整数/1 位小数，不依赖
+    MicroLIB 的 atof/strtod）；
+  - `cli_parse_hex()`：手写十六进制整数解析（可带 `0x` 前缀）；
+  - `CmdDisp`：`disp <value> [f] [hex]`——默认十进制 °C；`f` 点亮 °F 指示段
+    （DIG6 A6）；`hex` 按十六进制整数显示；先扫模式标志再按进制解析数值，
+    调 `display_set(value, type, base)` 后回显；
+  - 命令表注册：`disp <value> [f] [hex]: set 7-seg display value`。
+- 版本：APP `V1.00.31` → `V1.00.32`（`APP_FW_VERSION_NUM` 0x0001001F →
+  0x00010020）。Boot 不动（仍 V1.00.07）。
