Key features implemented: - Updated package metadata and dependencies in PKG-INFO, setup files - Added main.py entry point for backward compatibility with README launch method - Enhanced CLI with config options, system info command, and proper signal handling - Implemented minimal PluginManager loading only plugin-loader core plugin - Refactored PluginLoader to follow minimal core design, removed sandbox/isolation complexity - Updated auto-dependency plugin with safer PL injection mechanism and disabled pl_injection - Removed legacy plugin files (firewall, frp_proxy, ftp_server, multi_lang_deploy, ops_toolbox, security_gateway) as functionality moved to core plugin system - Improved gitignore with comprehensive ignore patterns The changes implement a minimal core framework design where only the plugin-loader is directly loaded by the core, with all other plugins managed through the PL injection mechanism, significantly simplifying the architecture.
