Removes the `ToolHistoryManager` and its associated functionalities, including history recording, querying, and prompt generation. This simplifies the architecture by decoupling tool execution history from the core logic.
The tool caching mechanism is now directly integrated into the `ToolExecutor` by wrapping the `execute_tool_call` method. This ensures that caching is applied consistently for all tool executions that have it enabled, improving performance and reducing redundant calls.
- Deletes `src/common/tool_history.py`.
- Removes tool history related functions from `prompt_builder.py` and `tool_api.py`.
- Adds a `wrap_tool_executor` function in `cache_manager.py` to apply caching logic directly to the `ToolExecutor`.
Refactored the web search plugin by removing the old Bing search implementation and reorganizing the plugin structure. Introduced modular search engine classes under 'web_search_tool/engines' and utility tools under 'web_search_tool/tools' and 'web_search_tool/utils'. Updated references and initialization logic to support multiple search engines and improved maintainability. Also performed minor code cleanups and replaced 'except ...: pass' with 'except ...: ...' for brevity.
Moved statistics update to only occur when the anti-injector system is enabled. Enhanced statistics reporting to handle disabled state and improved uptime calculation to use session start time. Updated status command to provide clearer feedback when the anti-injector system is disabled or when errors occur. Also fixed a docstring in prompt_builder.py for clarity.
