This commit introduces significant architectural enhancements to optimize performance and reduce battery usage for the Hiddify fork.

Key Features:
- **BatterySaverService**: Integrates `battery_plus` to monitor power states and suspend heavy tasks (like background profile updates and ping tests) when the device is low on battery or in power-save mode.
- **BenchmarkCacheManager**: Implements intelligent caching of ping benchmarks to avoid repetitive testing of the same nodes within a short timeframe.
- **SmartDiagnosticsService**: Evaluates connection errors in real-time, deducing the root cause (DNS, MTU fragmentation, IPv6, routing) and suggesting actionable fixes via the UI instead of opaque errors.
- **CloudflareScannerService**: A background scanner leveraging `dart_ping` that evaluates candidate Cloudflare IP addresses by latency and packet loss while respecting battery save states.
- **PerformanceDashboardWidget**: A UI component that displays critical real-time performance metrics (Ping, Node Score, Packet Loss, Uptime, Battery Impact) integrated directly into the `HomePage`.

All added services conform to the app's standard Riverpod + Clean Architecture pattern. Tests were written to ensure the new services operate correctly.

feat: Add Premium battery-saving, caching, diagnostics, and dashboard

- Added `msix` to `pubspec.yaml` `dev_dependencies` so that the `fastforge` command inside `make windows-msix-release` can successfully build the Windows msix package.
- Added `analyzer: ^7.0.0` to `pubspec.yaml` `dev_dependencies` to resolve the version incompatibility with riverpod_generator that was preventing `build_runner` from generating the `.g.dart` files. Without these generated files, the Android APK build fails because the generated providers are missing.
- Updated `.github/workflows/build.yml` to copy APK files from both `build/app/outputs/flutter-apk/` and `build/app/outputs/apk/release/` to correctly support workflows depending on Android abi splits configuration in newer gradle and flutter setups.

- Added `msix` package to `pubspec.yaml` `dev_dependencies` to ensure the fastforge command completes successfully for the msix targets.
- Updated `analyzer` constraint to `>=7.0.0` in `pubspec.yaml` `dev_dependencies` to avoid version incompatibility with riverpod_generator that was preventing `build_runner` from generating `.g.dart` files.
- Modified `.github/workflows/build.yml` to gracefully retrieve output APKs from both `build/app/outputs/flutter-apk/` and `build/app/outputs/apk/release/` depending on flutter and gradle release configurations and splitting structures.

- Added `msix` package to `pubspec.yaml` `dev_dependencies` to ensure the `fastforge` script correctly compiles MSIX targets for Windows.
- Added `analyzer: ^7.0.0` to `pubspec.yaml` `dev_dependencies` to prevent version incompatibility with `riverpod_generator`. This ensures `build_runner` functions correctly to generate `.g.dart` files required for Android APK builds.
- Refactored `.github/workflows/build.yml` Android APK target output discovery. Copied files from both `build/app/outputs/flutter-apk/` and `build/app/outputs/apk/release/` depending on ABI splits configurations in the active flutter/gradle toolchain structure.

- Add `msix` to `pubspec.yaml` `dev_dependencies` to ensure the `fastforge` script successfully compiles Windows MSIX releases during CI.
- Define `analyzer: ^7.0.0` in `dev_dependencies` to resolve version incompatibilities with `riverpod_generator`. This enables `.g.dart` file generation, allowing `flutter build apk` to succeed locally and in workflows.
- Update `.github/workflows/build.yml` to fallback properly to `build/app/outputs/apk/release/` instead of failing if older `build/app/outputs/flutter-apk/` isn't found. This guarantees APK uploads will not error out silently.
- Fix Apple upload actions conditional statements requiring empty checks to ensure they don't break macOS pipeline builds in GitHub workflows.
