refactor(Core): decompose handleResponse and add ToolCallingRender system

- Extract handleResponse into focused helpers: processToolCall, findTool,
  reportToolNotFound, renderToolCalling, executeToolCall
- Introduce ToolCallingRender sealed interface (Suppress/Default/Custom)
  allowing tools to control how their invocations are rendered
- Add printToolCalling to PrintAdvanceMessageHandler contract
- Implement default tool calling rendering in PrintMessageHandler (blue text)
- Add WriteFileTool for file writing capabilities
- Fix "responce" → "response" typo across Java and Python files
- Improve PythonRunner docker error handling and output messages
- Update Gradle test configuration (maxHeapSize, test logging)
