Subject: [PATCH] fix: Add final type casting for remaining type-checker issues
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add cast import and type casting in tool_utils.py for ToolUsage constructor
- Add cast import and type casting in lite_agent.py for execute_tool_and_check_finality call

These changes complete the type-checker fixes for hosted tools implementation.
