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.
This commit refactors the tool caching system to be more robust, configurable, and easier to use. The caching logic is centralized within the `wrap_tool_executor`, removing the need for boilerplate code within individual tool implementations.
Key changes:
- Adds `enable_cache`, `cache_ttl`, and `semantic_cache_query_key` attributes to `BaseTool` for declarative cache configuration.
- Moves caching logic from a simple history-based lookup and individual tools into a unified handling process in `wrap_tool_executor`.
- The new system leverages the central `tool_cache` manager for both exact and semantic caching based on tool configuration.
- Refactors `WebSurfingTool` and `URLParserTool` to utilize the new declarative caching mechanism, simplifying their code.
