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 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
