Refactor print statements for consistency and clarity across multiple files; remove unnecessary imports and improve code readability in pin_locator.py, routing.py, symbol_creator.py, wire_manager.py, factory.py, ipc_backend.py, kicad_interface.py, resource_definitions.py, test_ipc_backend.py, kicad_process.py, platform_helper.py, test_platform_helper.py. Add French README for KiCAD MCP Server with detailed features, installation instructions, and usage examples.
