初始导入：PhoneRail 五路手机直供电源板

原理图/PCB 已在 EasyEDA 里做到 12 页跨页 0 漏接，固件刚完成骨架包 A1。
这次是把已有的一切一次性纳入版本控制，没有改动任何设计内容。

纳入：
- 设计与需求文档、PROGRESS.md、小米8 参考原理图 PDF 与追脚脚本
- .claude/ 下的 EasyEDA 桥接工具链与几何/网表缓存（eda-parts.json、
  pcb-parts.json、pcb-pads.json、p2-ch1.json 等，是重画各页的唯一事实来源）
- 117 张验证截图（本项目所有方向问题都是靠人眼看截图发现的，属于证据不是垃圾）
- firmware/ 的 A1 骨架与 site/ 文档站源码

.gitignore 排除：构建产物（firmware/build、host/build、sdkconfig）、
site/node_modules、__pycache__、桥接日志 _bridge.log、脚本自标的 *.stale。

.gitattributes 默认 `* -text`：现有 .py/.json 大多是 CRLF，原样存，
不让 git 重写行尾。唯一例外是 *.sh 强制 LF —— 带 \r 的 shell 脚本 bash 跑不了。
