feat: 引入輕量級 MicroG 支援與 GMS 請求重導向機制

為 NPatch 引入了原生的 MicroG 整合支援，允許修補後的 Google 應用程式（例如 YouTube）在依賴 Google Play 服務的環境下，透過社群版 MicroG（如 ReVanced GmsCore）正常運作。

詳細改動範圍包含：

* ** UI Manager **
  - 於 `NewPatchScreen` 的修補選項清單中，新增「啟用 MicroG 支援」核取方塊與相容性說明。
  - 更新 `NewPatchViewModel`，透過 `Patcher.kt` 將使用者的 `useMicroG` 選擇狀態以 `--useMicroG` 指令列參數的形式，傳遞給底層修補引擎。

* ** Patcher **
  - 於 `NPatch.java` 中新增對 `--useMicroG` 參數的解析邏輯。
  - 擴充 `modifyManifestFile` 邏輯：當啟用 MicroG 支援時，自動讀取目標應用的原始簽名並轉碼為 Hex 格式。
  - 於 `AndroidManifest.xml` 中動態注入 `fake-signature` 的 `<meta-data>` 節點與 `android.permission.FAKE_PACKAGE_SIGNATURE` 權限，以滿足 MicroG 進行簽名欺騙（Signature Spoofing）時的驗證需求。

* ** Patch Loader **
  - 實作 `GmsRedirector.java` 類別，負責在應用程式執行期間動態攔截並重導向 IPC 通訊：
    1. 掛鉤 `Intent.setPackage`、`Intent.setComponent` 與建構子，將所有指向 `com.google.android.gms` 與 GSF 的意圖，強制導向至設備上已安裝的社群版 MicroG 套件（優先支援 `app.revanced.android.gms` 與 `org.microg.gms`）。
    2. 掛鉤 `ContentResolver`，替換帶有 GMS Authority 的 URI。針對真實 GMS 拋出的 `SecurityException`（憑證拒絕存取）實作了智慧攔截與重試機制。
    3. 掛鉤 `PackageManager.getPackageInfo` 實現動態簽名偽裝，使修補後的應用程式將 MicroG 視為官方正版 GMS。
  - 於 `LSPApplication.java` 的 `onLoad` 階段，依據 `PatchConfig` 設定檔動態喚醒並初始化 `GmsRedirector`。

* ** Share **
  - 更新 `PatchConfig.java` 以儲存與傳遞 `useMicroG` 布林值狀態。
  - 於 `Constants.java` 中定義 `REAL_GMS_PACKAGE_NAME` 常數，供各模組統一呼叫。
