docs: update README

Lower default cache size from 16MB to 4MB and journal size limit from 16MB to 4MB. Change MMapSizeBytes handling so 0 explicitly disables mmap instead of being overwritten with a 32MB default; negative values are normalized to 0. Update tests to match the new default journal size limit.

-Komariは、サーバーのパフォーマンスを監視するためのシンプルで効率的なソリューションを提供することを目的とした、軽量の自己ホスト型サーバー監視ツールです。Webインターフェースを介してサーバーのステータスを表示し、軽量エージェントを介してデータを収集します。
-
-[ドキュメント](https://komari-document.pages.dev/) | [Telegramグループ](https://t.me/komari_monitor)
-
-## 特徴
-
-- **軽量で効率的**: リソース消費が少なく、あらゆる規模のサーバーに適しています。
-- **自己ホスト型**: データプライバシーを完全に制御でき、展開も簡単です。
-- **Webインターフェース**: 直感的な監視ダッシュボードで、使いやすいです。

-
-1Panel アプリストアで利用可能です。「アプリストア」>「ユーティリティ」>「Komari」からインストールしてください。
-
-### 1. ワンクリックインストールスクリプトを使用する
-
-systemdを使用するディストリビューション（Ubuntu、Debianなど）に適しています。
-
-```bash
-curl -fsSL https://raw.githubusercontent.com/komari-monitor/komari/main/install-komari.sh -o install-komari.sh
-chmod +x install-komari.sh
-sudo ./install-komari.sh
-```
-
-### 2. Docker展開
-

-   ```bash
-   mkdir -p ./data
-   ```
-2. Dockerコンテナを実行します:
-   ```bash
-   docker run -d \
-     -p 25774:25774 \
-     -v $(pwd)/data:/app/data \

-   ```
-   ステップ1で生成された静的ファイルを `komari` プロジェクトのルートにある `/web/public/defaultTheme/dist` フォルダにコピーし、`komari-theme.json` と `preview.png`/`perview.png` を `/web/public/defaultTheme` にコピーします。
-   ```bash
-   go build -o komari
-   ```
-3. 実行:
