refactor: Move large binary files to releases and improve project structure

- Remove large binary files from git tracking:
  - libXray.aar (81MB)
  - LibXray.xcframework (495MB total)
  - geoip.dat (19MB)
  - geosite.dat (2.2MB)
- Update .gitignore to exclude all binary dependencies
- Add BINARY_DEPENDENCIES.md with download instructions
- Add setup_dependencies.sh script for easy dependency management
- Clean up build directories to reduce repository size

This follows git best practices by keeping the repository lightweight
and providing clear instructions for obtaining required dependencies.

+
+### iOS
+
+4. **LibXray.xcframework** (495MB total)
+   - Location: `ios/Frameworks/LibXray.xcframework`
+   - Download from: [libXray Releases](https://github.com/2dust/AndroidLibXrayLite/releases)
+
+### Assets (for both Android and iOS)
+
+2. **geoip.dat** (19MB)

+
+3. **geosite.dat** (2.2MB)

+
+## Setup Script
+
+You can use the following script to download and setup all required files:
+
+```bash
+#!/bin/bash
+# setup_dependencies.sh
+
+echo "Setting up binary dependencies for VPNclient Engine Flutter..."
+
+# Create directories
+mkdir -p android/libs
+mkdir -p android/src/main/assets
+mkdir -p ios/Resources/dat
+
+# Download libXray.aar (you need to get the latest release)
+echo "Please download libXray.aar manually from libXray releases and place it in android/libs/"
+
+# Download geo data files
+echo "Downloading geo data files..."
+curl -L -o android/src/main/assets/geoip.dat https://github.com/v2fly/geoip/releases/latest/download/geoip.dat
+curl -L -o android/src/main/assets/geosite.dat https://github.com/v2fly/domain-list-community/releases/latest/download/dlc.dat
+
+# Copy to iOS location
+cp android/src/main/assets/geoip.dat ios/Resources/dat/
+cp android/src/main/assets/geosite.dat ios/Resources/dat/
+
+echo "Binary dependencies setup complete!"
+```
+
+## Build Instructions
+
+1. Clone this repository
+2. Run the setup script or manually download the files as described above
+3. Run `flutter pub get`
+4. Build your project as usual
+
+## Note
+
+These files are excluded from the repository to:
+- Keep the repository size reasonable
+- Avoid licensing issues with binary distributions
+- Allow users to get the latest versions directly from official sources
