d8df5d49d3 fix: 修复 main.c/event.c/lcd.c 的中文注释乱码，统一为 UTF-8 编码 
lcd.c 原本整体是 GBK 编码，直接转码即可。main.c 与 event.c 曾被
Keil 环境以错误编码保存导致部分注释损坏，本次以历史提交中未损坏的
版本为基底恢复正确注释文本，并将其后新增的真实代码改动（RGB 三色
诊断指令、SOS 按键状态机解锁）对应的注释一并还原，不涉及任何代码逻辑变更。

## Git Workflow Requirements
- You must make a separate Git commit immediately after completing every individual, logical task (e.g., a bug fix, feature addition, or test case addition).
- Never accumulate multiple independent features or fixes into a single chunk of work.
- Automatically stage the files and generate a commit message matching Conventional Commits standards (e.g., `feat(auth): add login validation`).
- Do not ask for user confirmation before running `git add` and `git commit` locally.
- each `git commit` message must not more 100 words
- always increase APP_VERSION after each change.
