eisland-dev-add-svg-icon

Add a new SVG icon to the project's icon enum system with matching test assertions. Use this skill whenever the user asks to "add SVG icon", "添加图标", "add icon enum", "注册图标", "补齐图标枚举", "add SVG enum", or wants to register a new .svg file in the SvgIcon utility. Also trigger when the user provides a path to an .svg file and asks to create enum/test for it.
