Add supportsImages option to read_file tool and update docs

Introduces a supportsImages option to the read_file tool, updating its description to document image file support when enabled. Updates related tests and propagates the option through getNativeTools and buildNativeToolsArray to allow dynamic configuration based on model capabilities.
