 * Smart type coercion: converts common shorthand formats to GDScript-compatible values.

 * Supported conversions:
 * - Hex color strings (#RGB, #RRGGBB, #RRGGBBAA) → "Color(r, g, b, a)"
 * - Named CSS colors (13 most common) → "Color(r, g, b, a)"
 * - Comma-separated numbers ("x,y") → {x, y} / "x,y,z" → {x, y, z}
 * - Rect2-like objects ({x, y, w, h}) → "Rect2(x, y, w, h)"
