Driver Manager v2.0.0 - LSPosed-style rewrite

Complete rewrite with:
- Per-app driver scoping via mount namespace isolation (LSPosed-style)
- System-wide driver mode selection
- .ko kernel module manager with autoload and dependency tracking
- Driver integrity protection (monitor/enforce modes)
- Driver registry with auto-discovery and SHA256 hashing
- LSPosed-style dark WebUI with 6 tabs: Dashboard, Drivers, Apps, Modules, Protection, Logs
- RESTful API handler for WebUI communication
- Zygote process monitor for auto-applying scopes to new app launches
