Refactor tool tests and improve tool argument handling

Refactored integration tests to use a reusable employeeFinderTool method and improved assertions for tool call results. Updated tool argument formatting in OllamaAPI for clearer output. Modified AnnotatedTool to use 'numberOfHearts' instead of 'amountOfHearts' and simplified the sayHello method signature and output. Removed redundant and duplicate test code for tool streaming.
