Introduces the PlusCommand system for simplified command development, including new base classes, argument parsing utilities, and registration logic. Updates the plugin system, component registry, and bot message handling to support PlusCommand components alongside traditional commands. Adds documentation and configuration for command prefixes, and provides a developer guide for the new system.
Refactored configuration classes to inherit from a new ValidatedConfigBase using Pydantic for robust validation and error reporting. Updated api_ada_configs.py, config.py, config_base.py, and official_configs.py to replace dataclasses with Pydantic models, add field validation, and improve error messages. This change enhances configuration reliability and developer feedback for misconfigurations. Also includes minor code cleanups and removal of unused variables in other modules.
