fix: scope playback operation logs to JST service date

position-api(D1)側の位置マスターは更新が止まっているため、mockモードの
Pos補完をbackendの位置マスターに切り替える。レスポンス形式の差
({data:[]}包み、pos_numが文字列、pos_type→position_kind、pos_textのnull)
はpositionMasterParserで旧形式に変換する。

 ## 🛠️ セットアップ
 
 ### 必要環境
-- Node.js 18以上
-- npm または yarn
-- Expo CLI
+- Node.js（Expo SDK 57が対応するLTS。`yarn expo:doctor` で確認）
+- Yarn（lockfileは `yarn.lock` のみ）
+- EAS CLI（ビルドする場合）
 
-### インストール
+### インストールと起動
 
 ```bash
-# 依存関係のインストール
-npm install
+# 依存関係のインストール（postinstallでpatch-packageが実行されます）
+yarn install
 
-# 開発サーバー起動
-npm start
+# 開発サーバー起動（dev client）
+yarn start
 
-# iOS実行
-npm run ios
+# ネイティブビルドして実行
+yarn ios
+yarn android
+```
 
-# Android実行
-npm run android
+### 検証
 
-# Web実行
-npm run web
+```bash
+yarn typecheck   # tsc --noEmit
+yarn lint        # expo lint
+yarn test        # tests/*.test.ts
+yarn verify      # 上記3つをまとめて実行
+yarn expo:doctor # Expo依存関係の整合性チェック
+```
+
+### 依存ライブラリのライセンス一覧
+
+`dependencies` を追加・更新したら、アプリ内の「オープンソースライセンス」画面で使う一覧を再生成してください。再生成を忘れると `yarn test` が失敗します。
+
+```bash
+yarn licenses:generate  # assets/licenses/oss-licenses.json を更新
 ```
 
 ## 📝 開発ガイドライン
