Refactor anti-injection system and remove command skip list

Removed the command skip list feature and related code from the anti-injection system, including configuration options, plugin command collection, and management commands. Refactored anti-injector logic to operate directly on message dictionaries and simplified whitelist and message content extraction. Updated response handling to perform anti-injection checks before reply generation, and removed skip list refresh logic from the plugin manager.
