Gemini×Unityで作るカフェ経営ゲーム第7回：エリアマップと人件費UI

Unity 2022.3 (C#) で動作する「AreaMapManager.cs」を作成してください。

【要件】
1. ライバル店データ構造 `RivalStoreData`：
   - storeName (string), rating (float), marketShare (float)
   - weaknessList (List) : 「接客スピードが遅い」「メニュー価格が高い」「内装が古い」
2. エリア全体の市場シェア計算：
   - 自店舗評価（GameManager.Instance.currentRating）とライバル店評価の比率から自店舗市場シェア(%)を算出。
3. 出店可能地（Expansion Area）判定：
   - 資金￥50,000を支払い新店舗を開設する関数 `TryExpandNewStore()` の作成。
4. UIイベント通知：
   - System.Action OnAreaMapUpdated; // (自店シェア, 選択中ライバルデータ)
