refactor: notify/footer 持久配置收编到 config/，chrome bridge 地址固定

仓库规则要求 config/ 为唯一配置来源、不以环境变量作持久默认值：
- pi-notify 改读 config/pi-notify.json（逐字段校验回退，复用原 parsers 钳制）
- pi-minimal-footer 改读 config/pi-minimal-footer.json
- pi-chrome 移除 PI_CHROME_BRIDGE_HOST/PORT，固定 127.0.0.1:17318
  （浏览器端 service_worker.js 硬编码同一地址，单侧可配只会断连）

 ## Configuration
 
-Environment variables (all optional):
+Persistent defaults are read from `config/pi-minimal-footer.json` inside the installed bundle; a missing or invalid file falls back to the defaults shown:
 
-| Variable                        | Description                                              | Default |
-| ------------------------------- | -------------------------------------------------------- | ------- |
-| `PI_MINIMAL_FOOTER_SHOW_CWD`    | Show current working directory in footer status line     | `1`     |
-| `PI_MINIMAL_FOOTER_SHOW_BRANCH` | Show git branch/dirty/ahead/behind in footer status line | `1`     |
+| Field        | Description                                              | Default |
+| ------------ | -------------------------------------------------------- | ------- |
+| `showCwd`    | Show current working directory in footer status line     | `true`  |
+| `showBranch` | Show git branch/dirty/ahead/behind in footer status line | `true`  |
 
-Accepted false values: `0`, `false`, `no`, `off` (case-insensitive).
+Only `true`/`false` values are honoured; anything else falls back to the default for that field.
