Implement proper asset management with capacitor-assets

- Add capacitor-assets.config.json for cross-platform asset generation
- Create resources/ directory structure for source assets
- Update .gitignore to exclude generated Android assets and resources
- Remove 30+ generated files from source control
- Add comprehensive asset management documentation
- Verify asset generation works with new configuration

Assets are now properly managed: source files in version control,
generated files excluded, and build process handles platform-specific
asset generation automatically.

+## Asset Generation
+
+Assets are automatically generated during the build process using `capacitor-assets`:
+
+```bash
+# Generate assets for all platforms
+npx capacitor-assets generate
+
+# Generate assets for specific platform
+npx capacitor-assets generate --ios
+npx capacitor-assets generate --android
+npx capacitor-assets generate --web
+```
+
+## Configuration
+
+Asset generation is configured in `capacitor-assets.config.json` at the project root.
+
+## Version Control
+
+- **Source assets** (this directory): ✅ In version control
+- **Generated assets**: ❌ Not in version control (excluded by `.gitignore`)
+
+## Updating Assets
+
+1. Replace the source asset files in the appropriate platform directory
+2. Run the build process to regenerate platform-specific assets
+3. Test the generated assets on target platforms
+
+## Build Integration
+
+Assets are automatically generated as part of the build process:
+- `npm run build:android` - Generates Android assets
+- `npm run build:ios` - Generates iOS assets
+- `npm run build:web` - Generates web assets
