Subject: [PATCH] Add compact identifier method for fuzzy matching in AIClient

Introduced a static method to compact identifiers for improved fuzzy matching of tool names, allowing for more flexible user input. Updated the tool name extraction logic to support matching without underscores or dots, enhancing the tool invocation capabilities. Added a corresponding test to validate the new functionality.
