docs: drop the "Auto-update setup (maintainers)" section from READMEs

Maintainer-only setup steps don't belong on the public README — they're
runbook material, not user-facing docs. The README is now solely about
what the app is and how to use it.

-## Auto-update setup (maintainers)
-
-EchoWise ships with an in-app updater powered by `tauri-plugin-updater`. The desktop app polls a JSON manifest at app launch and from the Settings → About panel; when a signed bundle is newer than the installed version, the user can install it with one click.
-
-Out of the box the update check is wired up but **signing is unconfigured** — the app will run fine without it, but auto-update will be disabled until you set it up. To enable:
-
-### 1. Generate a signing keypair (one time)
-
-```bash
-npx @tauri-apps/cli signer generate -w ~/.tauri/echowise-updater.key
-```
-
-Two files are written:
-- `~/.tauri/echowise-updater.key` — **private** key. Store it somewhere safe (password manager, secrets vault). Never commit it.
-- `~/.tauri/echowise-updater.key.pub` — public key. Print and copy it.
-
-### 2. Embed the public key in `tauri.conf.json`
-
-```json
-"plugins": {
-  "updater": {
-    "active": true,
-    "pubkey": "<paste the content of echowise-updater.key.pub here>",
-    "endpoints": [
-      "https://github.com/hujiulin/EchoWise/releases/latest/download/latest.json"
-    ]
-  }
-}
-```
-
-Commit this change.
-
-### 3. Add GitHub repo secrets
-
-In GitHub → repository → **Settings → Secrets and variables → Actions**, add:
-
-| Secret | Value |
-|---|---|
-| `TAURI_SIGNING_PRIVATE_KEY` | Contents of `~/.tauri/echowise-updater.key` |
-| `TAURI_SIGNING_PRIVATE_KEY_PASSWORD` | The password you set in step 1 (or empty if none) |
-
-### 4. Ship a release
-
-Push a `v*` tag as usual. The release workflow will:
-- Build per-platform installers
-- Sign each updater bundle with your private key
-- Upload a `latest.json` manifest alongside the installers
-
-Existing users will see the update inside the app on next launch (after a quiet background check) and in **Settings → About → Updates**.
-
-### Endpoint format
-
-The `latest.json` file follows the [Tauri v2 schema](https://v2.tauri.app/plugin/updater/):
-
-```json
-{
-  "version": "0.2.0",
-  "notes": "What's new",
-  "pub_date": "2026-06-07T10:00:00Z",
-  "platforms": {
-    "darwin-aarch64": {
-      "signature": "<base64>",
-      "url": "https://github.com/.../EchoWise_0.2.0_aarch64.app.tar.gz"
-    },
-    "darwin-x86_64":  { ... },
-    "windows-x86_64": { ... }
-  }
-}
-```
-
-The release workflow generates this automatically when `TAURI_SIGNING_PRIVATE_KEY` is set.

-## 自动更新设置（维护者）
-
-EchoWise 内置基于 `tauri-plugin-updater` 的自动更新。桌面端启动时和 Settings → About 面板都会去拉一个 JSON manifest；当签名过的新版可用时，用户一键即可安装。
-
-更新检查的代码已经全部就绪，**但签名默认未配置** —— 不配置不影响应用使用，只是自动更新不会启用。开启步骤：
-
-### 1. 生成签名密钥对（一次性）
-
-```bash
-npx @tauri-apps/cli signer generate -w ~/.tauri/echowise-updater.key
-```
-
-会生成两个文件：
-- `~/.tauri/echowise-updater.key` —— **私钥**。妥善保管（密码管理器 / 密钥库），**绝不提交**。
-- `~/.tauri/echowise-updater.key.pub` —— 公钥。打开复制内容。
-
-### 2. 把公钥写进 `tauri.conf.json`
-
-```json
-"plugins": {
-  "updater": {
-    "active": true,
-    "pubkey": "<把 echowise-updater.key.pub 的内容贴在这>",
-    "endpoints": [
-      "https://github.com/hujiulin/EchoWise/releases/latest/download/latest.json"
-    ]
-  }
-}
-```
-
-提交这个改动。
-
-### 3. 加 GitHub 仓库 secrets
-
-到 GitHub → 仓库 → **Settings → Secrets and variables → Actions**，添加：
-
-| Secret | 值 |
-|---|---|
-| `TAURI_SIGNING_PRIVATE_KEY` | `~/.tauri/echowise-updater.key` 文件的内容 |
-| `TAURI_SIGNING_PRIVATE_KEY_PASSWORD` | 第 1 步设置的密码（没设就留空） |
-
-### 4. 发版
-
-像往常一样 push `v*` tag，release workflow 会：
-- 在三个平台打包安装器
-- 用你的私钥签名每个更新包
-- 在 Releases 一起上传 `latest.json` manifest
-
-现有用户下次启动 EchoWise 后，应用会在后台静默检查，并在 **Settings → About → Updates** 显示更新。
-
-### Endpoint 格式
-
-`latest.json` 遵循 [Tauri v2 schema](https://v2.tauri.app/plugin/updater/)：
-
-```json
-{
-  "version": "0.2.0",
-  "notes": "What's new",
-  "pub_date": "2026-06-07T10:00:00Z",
-  "platforms": {
-    "darwin-aarch64": {
-      "signature": "<base64>",
-      "url": "https://github.com/.../EchoWise_0.2.0_aarch64.app.tar.gz"
-    },
-    "darwin-x86_64":  { ... },
-    "windows-x86_64": { ... }
-  }
-}
-```
-
-`TAURI_SIGNING_PRIVATE_KEY` 配置后，release workflow 会自动生成这个文件。
