Add automatic application configuration for tmpfs caches

- Auto-detect and configure Firefox cache location in prefs.js - Auto-create optimized .desktop launchers for Chrome/Chromium/Brave - Auto-configure NPM and Pip cache directories - Auto-link KDE/Plasma thumbnail cache to tmpfs - Add configure_applications_for_tmpfs() function with smart detection - Backup original configs before modification - Set proper ownership and permissions for all cache directories - Replace manual setup instructions with automatic configuration - Show progress of configured applications with count - Update next steps to reflect automatic setup Benefits: - Zero post-setup manual configuration needed - Immediate performance improvement on app restart - Safer with automatic backups and proper permissions - Better user experience with clear progress reporting

 # Changelog

+## [2025-10-06] - Automatic Application Configuration
+
+### Added
+- **Automatic browser cache configuration**: Script now automatically detects and configures browsers
+  - Firefox: Automatically updates prefs.js with tmpfs cache location
+  - Chrome/Chromium: Creates optimized .desktop launchers with --disk-cache-dir flag
+  - Brave: Creates optimized .desktop launcher with tmpfs cache
+  - Automatic backup of original configurations before modifications
+  
+- **Automatic development tools configuration**:
+  - NPM: Automatically configures cache directory via npm config
+  - Pip: Creates pip.conf with tmpfs cache location
+  - Proper user/group ownership for all configured directories
+
+- **Automatic desktop environment integration**:
+  - KDE/Plasma: Automatically links thumbnail cache to tmpfs
+  - Proper symlink management with backup of existing directories
+
+- **Smart detection**: Only configures applications that are actually installed
+- **Progress reporting**: Shows which applications were successfully configured
+- **User guidance**: Clear instructions for restarting configured applications
+
+### Changed
+- Replaced manual configuration instructions with automatic setup
+- Improved user experience by eliminating post-setup manual steps
+- Updated "Next Steps" to reflect automatic configuration
+
+### Benefits
+- **Zero manual configuration** needed after running the optimizer
+- **Immediate performance boost** upon restarting configured applications
+- **Safer implementation** with automatic backups and proper permissions
+- **User-friendly** progress reporting during configuration
+
